Question

Which of the following is an even function?

f(x) = (x - 1)2
OMX) = 8x
O f(x) = x2-X
Of(x) = 7

Answer 1

7 is the answer to this because, (7-1)2=(6)2=12

Answer 2

F(X)=7 is the even function

Explanation:

f(x)=(x-1)2 is neither odd or even

f(x)=8x is a odd function

f(x)=x2-x is neither odd or even

and f(x)=7 is EVEN
