Question

Let g(x)=2x and h(x)=x^2+4. Find the value
(g o h) (0)

Answer 1

so (g o h)(0) means g(h(0))

Answer 2

first figure out h(0), than plug that into g for x

Answer 3

ok

Answer 4

Like this? 0=0^2+4

Answer 5

-4=0??

Answer 6

I think you mean h(0).
h(0) = 0^2 + 4
h(0) = 0 + 4
h(0) = 4

Answer 7

Ah ok

Answer 8

so now we know h(0) = 4 so we can do
g(h(0)) = g(4) right?

Answer 9

Yes

Answer 10

g(4) = 2(4)
g(4) = 8

Answer 11

so (g o h)(0) = 8

Answer 12

Ok great much easier to understand thank you

Answer 13

you're welcome
