Which equation for g(x) represents the transformation of f(x) given that f(x) = x^2
g(x) = f(x) shifted up 2 units
i have more translation of quadratics questions i need some help on so if you’re willing let me know
Answers
Answer:
g(x) = x² + 2
Step-by-step explanation:
If we want to shift a function down, we subtract the number we are asked to move outside the function's argument:
⇒ To shift f(x) b units down → f(x) - b
Similarly, in function notation, if we want to shift a function up, we add the number we are asked to move outside the function's argument:
⇒ To shift f(x) b units up → f(x) + b
Given function f(x) = x²
Shift 2 units up ⇒ x² + 2
Therefore, g(x) = x² + 2

Answer:
Step-by-step explanation:
(x +1)² + (x +1)(5x - 3) = (x +1)(x+1) + (x +1)(5x - 3)
(x +10 is the common term. SO, we can take out (x+1)
=(x +1) [ x + 1 + 5x - 3]
=(x + 1) (x + 5x + 1 - 3) {Combine like terms}

Step-by-step explanation:
Question 1:
In a function, every output value corresponds to exactly one input value.
The words that should be switched around are "output" and "input". This is because every input should have have only ONE output.
Question 2:
The following graph fails the vertical line test and is not a function. (YES)
Using the vertical line test to test whether the vertical line passes through the graphed function more then once. If it does, its not a function. If it doesn't, it is a function. Sadly, the vertical lines pass the point on two separate occasions which makes it not a function.
The vertical line shows gives the points (4, 2) and (4, -2).

Hey there!
First of all, the quotient of a number and 6 means you divide that number by 6.
Let the number be x.
Then, eight more means you add 8:

If x = 5 units, y = 15 units, and h = 8 units, find the area of the parallelogram shown above using decomposition. OA. 120 square units OB. 40 square units OC. 160 square units OD. 80 square units
Answers
Answer:
160 square units
Step-by-step explanation:
First, lets focus on the triangles.
To find the area of a right triangle, we need to multiply the length by the width, and divide by 2.
(5 * 8) / 2 = 20
(And since there is two triangles, the area of the two is 40.)
To find the area of a rectangle, we need to multiply the length by the width.
15 * 8 = 120
Now we add all the areas together.
120 + 20 + 20 = 160
Is the answer is 160 square units.

The sum of the first five terms of this sequence is 228
Work out the value of a,
Answers
We will see that the value of a is 12.
How to get the value of a?
We have a Fibonacci sequence, and the first four terms are:
a, 2a, 3a, 5a.
Because it is a Fibonacci sequence, the next term should be the sum of the two previous ones.
3a + 5a = 8a
Then the sum of the first 5 terms is:
(a + 2a + 3a + 5a + 8a) = 228
We can solve this for a.
(1 + 2 + 3 + 5 + 8)*a = 228
19*a = 228
a = 228/19 = 12
So we conclude that the value of a is 12.

At book fair, the ratio of adults to children is 7 : 3
The ratio of girls to boys at the book fair is 4 : 1
What percentage of the people at the book fair are boys?
Answers
The percentage of the boys at the book fair is 6%
What is a percentage?Percentages are used in mathematics as a decimal ratio expressed in a fraction of 100. It is represented with a symbol known as %.
At a book fair, the ratio of adults to children are:
7 : 3
The total number of people at the book fair = 7 + 3 = 10
The percentage of adults are:
[tex]\mathbf{=\dfrac{7}{10}\times 100\%}[/tex]
= 70% are adults
The percentage of children are:
[tex]\mathbf{=\dfrac{3}{10}\times 100\%}[/tex]
= 30% are children
However, if from the children, 4 are girls and 1 is a boy.
The total number of children at the fair = 4 + 1 = 5
The percentage of girls are:
[tex]\mathbf{=\dfrac{4}{5} \times 30\%}[/tex]
= 24%
The percentage of boys at the book fair is:
[tex]\mathbf{=\dfrac{1}{5} \times 30\%}[/tex]
= 6%
