You should use your diagram you made in a) to help you.

After making part a), you'll see that there are two points of intersection.

First, solve for x being positive, rejecting one value. Your diagram would tell you which one to reject.

Then, do the same thing with the negative value of x.

Finally, you should get

x = 2
