Question

Let Q(x) =x^3+7x^2+8x-13 and P (x)=x+2. Use the graphing capabilities of your graphing calculator to solve the following.
a. P(x) =Q(X)
b. P(X)< Q(x)

Answer 1

So, do you have a graphing calculator? Do you know how to use it? Graph the two equations. The points where they cross are the points where P(x) = Q(x); you'll need to look at the graph and see the value of x at each point.

For the second part, look at the graph and determine the ranges of x where the Q(x) graph is above the P(x) graph (greater y values).
