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.

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
