Question

Am I right or wrong?
If h(x)=(fog)(x) and h(x)=4 sqrt x+7, find g(x) if f(x)=4 sqrt x+1
I worked it out, but different answers a couple of times.

Answer 1

i would say \(g(x)=x+6\)

Answer 2

7then
\[f(g(x))=f(x+6)=4\sqrt{x+6+1}=4\sqrt{x+7}\]

Answer 3

@satellite73 so 7 is the answer?

Answer 4

?

Answer 5

\[\large g(x) = x + 6\] as stated above

Answer 6

maybe i am not reading the question correctly
a screen shot or an equation editor would help on this one

Answer 7

@satellite73 You're right, sorry. I looked at it wrong. Thank you! :)
