Which functions are even? check all of the boxes that apply. f(x) = x4 – x? f(x) = x2 – 3x + 2 f(x) = (x - 2) f(x) = x done

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,

The function is not even.

This function is not even

This function is also not even

This function is also not even..

A and D

Step-by-step explanation:

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

there is no
