y = sec(x) has a range of f(x) ≤ -1 and f(x) ≥ 1
Thus does not include zero in the range scale.
Extra's:
y = cos(x) has a range of -1 ≤ f(x) ≤ 1
y = cot(x) has infinity range
y = tan(x) has infinity range.
Answer:
sec x
Step-by-step explanation:
Let's set each function equal to zero to see if they have zero in their function.
If there is no solution, then we no solution of zero.
[tex] \cos(x) = 0[/tex]
[tex]x = \frac{\pi}{2} + 2\pi(n)[/tex]
So there is a solution of zero.
[tex] \cot(x) = 0[/tex]
[tex] \frac{ \cos(x) }{ \sin(x) } = 0[/tex]
There answer here is
[tex]x = \frac{\pi}{2} + 2\pi(n)[/tex]
So there is a solution. of zero here
If cot x=0, has a solution of zero, then tan x does as well. Since we can use
[tex] \frac{ \sin(x) }{ \cos(x) } = \tan(x) [/tex]
[tex] \frac{ \sin(x) }{ \cos(x) } = 0[/tex]
The answer here will be
[tex]0 + 2\pi(n)[/tex]
So that leaves sec x.
Proof:
[tex] \sec(x) = \frac{1}{ \cos(x) } [/tex]
1 divided by any number won't equal zero, so the solution will never be 0.

x ≤ 9
Step-by-step explanation:
Step 1: Write inequality
x - 9 ≤ 2(9 - x)
Step 2: Solve for x
Distribute 2: x - 9 ≤ 18 - 2xAdd 2x on both sides: 3x - 9 ≤ 18Add 9 to both sides: 3x ≤ 27Divide both sides by 3: x ≤ 9Here we see that any solution less than or equal to 9 would work.
Answer:
x ≤ 9
Step-by-step explanation:
x -9 ≤ 2(9 -x)
x -9 ≤ 18 -2x
+2x +2x
3x -9 ≤ 18
+9 +9
3x ≤ 27

Answer:
The biggest differentiating factor between a function and NOT a function
is that a function gives only one output for any given input. so no matter how many times you use the same value in the function, you will get the same output
A relation which is not a function will have 2 or more outputs for a single input
So if we have more than 1 similar input values in the table and given them different outputs, the relation will NOT be a function
I will take 2 similar inputs "1" and give them different outputs, the rest of the table can be randomly filled

If five residential subscribers are randomly selected from a city on this island find the probability of each of the following events.
a. All five qualify for the favorable rate
b. At least four qualify for the favorable rates
Answers
Answer: a. 0.00032 B. 0.00672

Given: Proportion of island residents of a country have reduced their electricity usage (p) = 20%= 0.20
Here, residents have two choices either reduced electricity usage or not , hence it follows binomial distribution

You can prove 5/10 isn't equivalent to 1/6 by simply reducing 5/10.
[tex]\frac{5}{10}[/tex]
