Question

Which functions are even? Check all of the boxes that apply.

Answer 1

Answer:

None of the functions is even

Step-by-step explanation:

In order to check the function is even or odd, we put -x in the function, if the answer is as it is as the original function then the function is even.

So,

$1.\ f(x) = x^4-x\\f(-x) = (-x)^4-(-x)\\f(-x) = x^4+x$

The function is not even.

$2.\ f(x) = x^2 – 3x + 2\\f(-x) = (-x)^2-3(-x)+2\\f(-x)= x^2+3x+2$

This function is not even

$3.\ f(x) = (x - 2)\\f(-x) = -x-2$

This function is also not even

$4.\ f(x) = x\\f(-x) = -x$

This function is also not even..

Answer 2

Answer:

A and D

Step-by-step explanation:

solve for each with f(x)= f(-x)
