Answer:
a) 6 b) 1 c) 9 d) -9
Step-by-step explanation:
a) go to -8 on the x-axis. Then go to the graph and see what the y value is.
I get 6. Therefore, f(-8) = 6
Do the same thing for b)
b) f(0) = 1
c) Go to -5 on the y-axis. Then go to the graph and see what the x value is
I get 9. Therefore f(9) = -5
Do the same thing for d)
d) f(-9) = 7
And that's how you use the graph to answer those questions. OK?
