sketch a function with the following characteristics:
f(0) = 1
f'(x) is greater than or equal to 0 for x greater than -2
f'(x) is less than 0 for x less than -2
f'(-2) = 0
f'(2) = 0
These guys are stationary points, could mean your function is a cubic! Or maybe higher order if they are points of inflection.
