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
This is just a (x,y) point so start by plotting this.
These guys are stationary points, could mean your function is a cubic! Or maybe higher order if they are points of inflection.
These guys describe the gradient, as f'(x)>0 for x>-2 therefore f'(2) = 0 is a point of inflection.
Enough hints?
