Question

Find f(x) and g(x) so the function can be expressed as y = f(g(x)).

y = Two divided by x squared. + 3
\[\frac{ 2 }{x^2}+3\]

Answer 1

there are lots of ways to do this

Answer 2

you could say \(g(x)=x^2\) and \(f(x)=\frac{1}{x}+3\) for example

Answer 3

oops no, \(f(x)=\frac{2}{x}+3\)

Answer 4

or you could say \(g(x)=\frac{2}{x^2}\) and \(f(x)=x+3\)

Answer 5

or \(g(x)=\frac{1}{x^2}\) and \(f(x)=2x+3\)

Answer 6

i bet you can make up another one if you try

Answer 7

omg thanks!
