Question 701800: Hi, I'm trying to solve this:

Answer by josgarithmetic(39620) (Show Source): You can put this solution on YOUR website!
Graph the portion of the function which is in the domain between -1 and 5, inclusive; ALL of the function in that domain.

The righthand endpoint is (5, 42), and the lefthand endpoint is (-1, 0). You made some mistake in computing your point of (-1, -2).
