Which functions are even? Check all of the boxes that apply. F (x) = x Superscript 4 Baseline minus x squared f (x) = x squared minus 3 x + 2 f (x) = StartRoot (x minus 2) EndRoot f(x) = |x|

4.

Step-by-step explanation:

We know that

If f(x)=f(-x)

Then, the function is called  even function.

1.

Hence, the function is not even.

2.

Hence, the function is not even.

3.

Hence, the function is not even.

4.

Therefore, the function is even.

Option (4) is true.

b

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
