If f(x)=4x+3 and g(x)=x^2-3 then f(g(2))

f(g(2))=7

Step-by-step explanation:

The Composite Function

Given f(x) and g(x) as real functions, the composite function is defined as:

It can be found by substituting g into f.

The given functions are:

It's required to find f( g( 2 ) )

Find g(2):

Operating:

g(2)=1

Now find f(1):

Thus:

f( g( 2 ) )=7
