Calculate the value of [tex]\( g(f(6)) \)[/tex].



Answer :

To solve the problem, we will follow these steps:

1. Step 1: Calculate [tex]\( f(6) \)[/tex]

The function [tex]\( f(x) \)[/tex] is defined as:
[tex]\[ f(x) = \frac{x}{2} + 5 \][/tex]

Substituting [tex]\( x = 6 \)[/tex] into the function [tex]\( f(x) \)[/tex]:
[tex]\[ f(6) = \frac{6}{2} + 5 \][/tex]
Simplifying the expression:
[tex]\[ f(6) = 3 + 5 = 8.0 \][/tex]

2. Step 2: Calculate [tex]\( g(f(6)) \)[/tex]

First, recall that we have already found [tex]\( f(6) = 8.0 \)[/tex].

Next, the function [tex]\( g(x) \)[/tex] is defined as:
[tex]\[ g(x) = 3x + 4 \][/tex]

So we need to find [tex]\( g(8.0) \)[/tex]:
[tex]\[ g(8.0) = 3(8.0) + 4 \][/tex]
Simplifying the expression:
[tex]\[ g(8.0) = 24.0 + 4 = 28.0 \][/tex]

Therefore, the value of [tex]\( g(f(6)) \)[/tex] is [tex]\( 28.0 \)[/tex].
