Hi,
x^3-3x^2+1
Note where the graph changes directions at the blue high point (0,1)
and at the red low point (2,-3)
relative maxima is f(0) = 1  and relative minima is f(2) = -3
{{{drawing(300,300,   -6, 6, -6, 6,  grid(1),
blue(circle(0, 1,0.3)),
red(circle(2, -3,0.3)),
graph( 300, 300, -6, 6, -6, 6,0, x^3-3x^2+1 ))}}}
