Question

What does the graph tell you about the value of c in this function?

Answer 1

The c value just shifts the graph up or down with respect to the x axis. Since the graph is shifted 4 units down from the x axis, the value of c is -4

Answer 2

so c is less than zero?

Answer 3

Answer 4

Yes, I'll post a graph of this function in a couple of minutes so you can see the effect of different values for c.

Answer 5

There are three graphs. Green with c=-4 Red with c=0 Purple with c=6

Notice how the red graph shafts up and down with the different values of c.
