Question

If h(x) = 6 – x, what is the value of (h*h)(10)

Answer 1

Hint :

(h*h)(10) = h(10) * h(10)

Answer 2

6-x(10) * 6-x(10)??

Answer 3

ah this isn't composite functions.. ok I got confused for a second
since we have h(x) = 6-x
and (h(x))(h(x)) we just multiply
(6-x)(6-x)
and then evaluate the result when x = 10

Answer 4

yay
16

Answer 5

or we could obtain the result a bit faster if we let x = 10 immediately and have
(6-10)(6-10)
oh cool you got it! :D

Answer 6

(-4)(-4) = 16

Answer 7

thank you!

Answer 8

\[36-6x-6x+x^2 \rightarrow 36-12x+x^2 \]
at x = 10
\[36-12(10)+(10)^2 = 36-120+100=16 \]
yay!
