Determine whether the function f(x) = 5x^2-5 is even, odd, or neither.

Question

Determine whether the function f(x) = 5x^2-5 is even, odd, or neither.

Answer 1

An even function is symmetric with respect to the y axis.  Or, f(x) = f(-x)

 

This function is symmetry with respect to the y axis, so it is even.
