The graph of y=h(x) is shown in red below. Compute h(h(7)).
(Assume grid lines are spaced 1 unit apart.)
Compute h(h(7)).
ok first, what is the value of h(7) ?
Please let smallbrain answer for him/herself.
7h^2?
Thanks for answering but you do not have the idea at all.
h(7) is a number.
Go across to 7 on the x axis, then go up to where the graph is. What is the y yalue of the graph at the x=7 point?
That is h(7)
+63
