First you calculate -f(x) and f(-x). Then compare the three equations. If f(-x) is equal to f(x) then the function is even. If f(-x)=-f(x) then the function is odd. If none of the equations are equal then it is neither odd nor even.
Work Step by Step
Use the definitions of even and odd functions to describe how you determine if a function is even or odd in your own words as above.
