Question

Find f(x) and g(x) so that the function can be described as y = f(g(x)).
y=2/(x^2) +9

Answer 1

g(x) = x^2

f(x) = 2/(x+9)

Answer 2

@keeponbleeding what are the choices?

Answer 3

wait how did that happen?

Answer 4

no multiple choices

Answer 5

is that y?
\[y = \frac{ 2 }{ x^2 }+9\]

Answer 6

yes

Answer 7

y = f(g(x)) means that g(x) is input for variable of f(x)

say f(x) = 2/? + 9 , this is general form so ? must be x^2
thus
g(x) = x^2

Answer 8

thanks! got it
