Question

Which of the following is not an equation of a simple, even polynomial function? (Select all to apply.)

Answer 1

Wouldn't it be y = | x |? I am not 100% positive but I'm pretty sure that you need to have a least one value. Again not 100% sure

Answer 2

Answer:

$y=x^3$

Step-by-step explanation:

A function is an even polynomial function when f(-x) is equal to f(x)

Lets check each option, replace x with -x and see whether we get same y equation

$y=|x|$, Replace x with -x

$y=|-x|=x$, for any x value the value of y is positive always. So it is an even function

$y=x^2$

$y=(-x)^2=x^2$ same as the given equation . So it is an even function

$y=x^3$

$y=(-x)^3=-x^3$ It is not same as the given equation . So it is not an even function

$y=-x^2$

$y=-(-x)^2=-x^2$ same as the given equation . So it is an even function
