Scroll Down to the bottom for surprise!

The graph of $y=f(x)$ is shown in red below. For how many values of $c$ is $f(c) = -1$?

There are 2 values of c such that f(c) = -1.

Not exactly, but nice try! Adding on to what guest said, all you have to do is see on the graph how many times the y is at -1. There is 4.

 

Also, even though the picture is pixalated, it is still very disturbing, and NOT a surprise at all. Can you edit your post to get rid of it? Thanks!
