Answer:
and
Step-by-step explanation:
Given : Equation .
To find : f(x) and g(x) so the function can be expressed as y = f(g(x)) ?
Solution :
Our aim is to express f as a function of g, where g is a function itself, of x.
In the expression,
We may notice two functions, the squaring x function, which may well be our g i.e.
The function is re-written as,
and the "7 divided by x, +10" function is
Therefore, and .
