Answer:
The answer to your question is f(x) =-
Step-by-step explanation:
g(x) = 9x - 8
f(x) = ?
h(x) = (f°g)(x) = 9 / (9x - 8)
Process
When we evaluate a function with another function, just substitute the second function in all the x of the first function.
From the information given we notice that g(x) = 9x - 8 and it is in the denominator of the function h(x). This means that before we substitute this value in f(x) there, there was a "x".
Then
f(x) =- so (f°g)(x) =-
or h(x) = -
