How many square units are in the area of the triangle whose vertices are the x- and y- intercepts of the function f(x)=(x−1)^2 (x+8)

Is that :   f(x) = (x-1)2 * (x+8)   ??

The x-intercepts are -8 and 1   --->   a distance of 9 (the base)

The y-intercept is 8 (the height)

 

Area  is  ½ · 9 · 8  =  36
