 Question 22130: Graph the polynomial function. f(x)=-3x(x+2)to the second powerAnswer by rapaljer(4667)   (Show Source): You can put this solution on YOUR website! This graph has roots (zeros or x-intercepts!) at x= 0 and at x= -2. If it were multiplied out, it would be basically a graph with degree (or order) of 3 and the leading coefficient is negative. This means that it will open up on the left, and down on the right, passing through the root at x= 0, and BOUNCING at x= -2, since (x+2) is raised to an even power (i.e., there is an even multiplicity of this root). All of this is theory of equations, but you can also graph it with a graphing calculator, and it should look like this: R^2 at SCC
