Assuming you meant

Then you can compose the function g(x)

With the function

Because f (g(x) ) means that you first find (calculte)

and second you divide 7 by g(x) to obtain 7 / [√(8x+10) ].
57 = 7 + 2x
50 = 2x
x = 25

Hope this helps a little!!
Answer:
f[g(1)]=6.
Explanation:
Given f(n) and g(n) defined below:

First, we evaluate g(1):

Therefore:

Therefore, f[g(1)]=6.
