I really dont know how to do this but my teacher says that every problem on the homework is correct.
Answer by texttutoring(324) (Show Source): You can put this solution on YOUR website!
f(8) means to find the y-value when x=8

Simply go along the x-axis until you find x=8, and then travel down to find the corresponding point. It is located at y=-5

For your graph,

f(8) = -5
