Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing, and the end behavior when the following changes are made. Make sure to account for even and odd functions.
When f(x) becomes f(x) − 3
When f(x) becomes −2 ⋅ f(x)
Answers
If f(x) - 3 is the new equation, it means there is a vertical translation of f(x) down 3 units. The y-intercept will decrease by 3 units. Areas of increasing on the function may be lessened as the function is being translated down 3 units. The areas of decrease will increase because the function is being translated down. End behaviour will not change from a translation as long as the function is continuous at each end, (not a finite function with end points). The evenness or oddness of f(x) will not change either.
Part B:
The y-intercept will be flipped horizontally about the x-axis and multiplied by 2. This will mean that if the y-intercept was positive, it will now be negative and vice versa. The increasing and decreasing regions of the graph will be flipped, so anywhere f(x) was positive will now be negative and vice versa. They will also be double what they were before because all values are multiplied by 2. The end behaviour will switch. If f(x) was from Quad1->Quad3 for example, it will now be Quad2->Quad4 because of the flip at the x-axis. The evenness and oddness of the function will not change seeing as the degree of f(x) is not affected.
18 vocabulary words learned in 2 hours; 27 vocabulary words learned in 3 hours
Answers
Answer: They are equivalent
Step-by-step explanation:
Here is the complete question:
18 vocabulary words learbed in 2 hours 27 vocabulary words learned in 3 hours Are they equivalent? Why
From the question, we are informed that 18 vocabulary words are learned in 2 hours. The number of words learned per hour will be:
= 18/2
= 9 words per hour.
27 vocabulary words learned in 3 hours. The number of words learned per hour will be:
= 27/3
= 9 words per hour.
Since they both have identical number of words learned per hour, it means that they're equivalent.

Therefore, ∠F ≅ ∠Q
m∠F = m∠Q
(2x + 10)° = (3x + 1)°
3x - 2x = 10 - 1
x = 9
m∠Q = (3x + 1)°

In 2006 the average ticket price for a national football league game was 62.38. Since then the cost has increased an average of $2.54 per year. Write a linear equation to represent the cost of C of an NFL ticket y years after 2006.
Answers
Answer:
y = 2.54x + 62.38
Step-by-step explanation:
Let x represent the duration or stipulated years after the year 2006
Let y represent the amount of ticket that is sold
Let m represent the average increase in the price every year
y = mx + c
y = 2.54 × x + 62.38
y = 2.54x + 62.38
Answer:
C=2.54y+62.38
c=2.54y+62.38
C=62.38+2.54y
or
c=62.38+2.54y

A train leaves the station at time = 0. Traveling at a constant speed, the train travels 330 kilometers in 3 hours. Answers parts a and b. A. Write a function that relates the distance traveled d to time t. The function that relates the distance traveled d to the time is.
Answers
Answer:
The function that relates the distance traveled d to the time t is
f(t) = 110t, where d = f(t)
Step-by-step explanation:
From the question, we were told that the train is At a constant speed, the train travels 330 kilometers in 3 hours
We were told to write function that relates the distance traveled d to the time t, we can do this by writing a linear equation with those functions
Since we are told that the train travels 330 kilometers in 3 hours, then we can say the train travel (330/3) kilometers in 1 hour which means it travel 110 kilometers in 1 hour
Then d= 110t---------------eqn(1)
If if t = 0, then d = 0, as well since at t=0 the train is at the station
At t = 1 then d = 110.
From equation (1) d can be replaced by f(t) then we have
f(t) = 110t----------------eqn(2)
Now we replace d by f (t), because d = f t):
f(t) = 120t
Therefore, The function that relates the distance traveled d to the time is f(t) = 120t

An ammonia and water mixture fills a five-gallon container. Eighty percent of the mixture is ammonia, but some of the mixture will be drained and replaced with pure water. If a five-gallon mixture of fifty percent ammonia is desired, how many quarts of the mixture need to be drained before the water is added, given that 4 quarts equals a gallon
Answers
Answer:
The volume of the 80% ammonia that is to be drained before water is added is 7.5 quartz
Step-by-step explanation:
The volume of the ammonia and water mixture = 5 gallons
The percentage of ammonia in the mixture = 80%
The volume of ammonia desired = 5 gallons
The percentage concentration of ammonia desired = 50%
The diluting solution = Pure water
The measure of 4 quarts = 1 gallon
Therefore, we have, by equivalence solutions;
80% × x gallon = 50% × 5 gallons
x gallon = 50% × 5 gallons/(80%) = 3.125 gallons
x = 3.125 gallons
The volume of the 80% ammonia that is to be drained = 5 gallons - 3.125 gallons = 1.875 gallons
4 quarts = 1 gallon
1 gallon = 4 quarts
∴ 1.875 gallons = 4 × 1.875 quartz = 7.5 quartz
The volume of the 80% ammonia that is to be drained before water is added = 7.5 quartz
Answer:
7.5

At the King School, 55% of the students take a bus to school. If 220 students take a bus to school, how many students are there in total?
Answers
Answer:
400 student
55/100 * x(unknown) = 220
55x/100 =220
CROSS MULTIPLY
55X = 22000
X = 22000/55
X = 400
The total number of students at the King School is 440.
Given that, at the King School, 55% of the students take a bus to school.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Let the total number of students be x
So, 55% of x =220
⇒ 55/10 ×x=220
⇒ 0.55x=220
⇒ x=220/0.55
⇒ x=440
Therefore, the total number of students at the King School is 440.
