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

(Assume grid lines are spaced 1 unit apart.)

We  want to  find   where  the y  value  of the  graph =   -1

 

Notice  that  the  graph intersects  the  line  y =  -1    at  4 places

 

So.....4  values of c   where this occurs

 

Hope  that makes sense  smiley
