Question 259878: Determine algebraically whether each function is even, odd, or neither.
a.f(x)=3x4
b.f(x)=7x3
Answer by nerdybill(7384) (Show Source): You can put this solution on YOUR website!
a.f(x)=3x^4
f(-x) = 3(-x)^4
f(-x) = 3x^4
This is an "even" function
(notice it did not change the sign of the function. It stayed positive.)
.
b.f(x)=7x^3
f(-x)=7(-x)^3
f(-x)=-7x^3
This is an "odd" function
(notice it changed to the opposite sign from positive to negative)
