Question

Find f(x) and g(x) so that the function can be described as y = f(g(x)).
y=9/sqrt5x+5

Answer 1

is it
\[y=\frac{9}{\sqrt{5x+5}}\]?

Answer 2

if so you have lots of choices
you could say \(g(x)=\sqrt{5x+5}\)and \(f(x)=\frac{9}{x}\)
or you could say \(g(x)=5x+5\) and \(f(x)=\frac{9}{\sqrt{x}}\)

Answer 3

there are lots of other possibilities too, see if you can find one

Answer 4

yes thank you!
