Question 165279
Sketch the graph for:
{{{P(x) = (x+1)(x-2)(x+3)}}} First, you want to perform the indicated multiplication. You can do this in steps:
{{{highlight((x+1)(x-2))(x+3) = highlight((x^2-x-2))(x+3)}}}={{{x^3+2x^2-5x-6}}}
So now you have:
{{{P(x) = x^3+2x^2-5x-6}}} and this is graphed below:
{{{graph(400,400,-5,5,-10,5,x^3+2x^2-5x-6)}}}
