There are 3 types of stationary points for functions: a maxima, a minima and a saddle point. They all occur when the derivative of a function, f(x), is equal to 0, e.g. f'(x)=0. Therefore in order to find...

Chain Rule: dy/dx = dy/du x du/dxy=e^3-2xSubstitute u for the power (3-2x) y = e^u u = 3-2xdy/du = e^u du/dx = -2dy/dx = -2e^u = -2e^3-2x
