Answer
a) Look below
b) You need to have a few points to make the graph of the function. The y-intercept is an easy point to obtain as it is just the last term in the equation.
Work Step by Step
a) The easiest way to make the graph is to find the x-intercepts and the y-intercepts, and connect them in a parabolic way. Alternatively, you can use other points. However, you should keep the y-intercept because that is the easiest point to obtain and graph. Check with a graphing calculator.
