14-3OddandEvenFunctionsEven Functions o Symmetric with respect to the y-axis. o f(-x) = f(x) o Note: Not all even degrees make an even function!
y=x2+2x+1
We will show algebraically that f(x) = 3x2 + 1 is an even function.

the x and y axis). o f(-x) = -f(x) o Note: Not all odd degrees make an odd function! y=x3+1
We will show algebraically that f(x) = 2x3 +3x is an odd function.
