Question

which of the following is an even function? A. y=x^5 - (sqaure root)xB. y=2+(absolute value) xC. y=x-5D. y+x^5 - x^3E. y=2x^3+4x

Answer 1

In the question, we are asked to find the even function.

Step-by-step explanation

A function is an even function if f of x is equal to f of −x for all the values of x. This means that the function is the same for the positive x-axis and the negative x-axis, or graphically, symmetric about the y-axis.

For

`y=2+|x|`

All the other functions apart from option A represent odd functions.

Answer: Option A
