Question

What is the main issue with plugging values into a function and then graphing it?

Too hard to calculate.
Takes too much time.
Never sure of exact data points.
Does not provide accurate results.

Answer 1

the answer is all of the above!

Answer 2

B: It takes too much time

Explanation:

Once the points have been calculated and then graphed, the solutions to y = 0 can be found. Look for y = 0 and the solutions are -5 and -1. But that takes a lot of time. There must be an easier way, and fortunately, there is.
