Question

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

y = 7/sqrt 8x +10

Answer 1

Assuming you meant


`y = (7)/( √(8x+10) )`

Then you can compose the function g(x)


`g(x)= √(8x+10)`

With the function


`f(x)= (7)/(x)`


Because f (g(x) ) means that you first find (calculte)
`√(8x+10)` and second you divide 7 by g(x) to obtain 7 / [√(8x+10) ].
