Answer :

Certainly! To evaluate the function [tex]\( g(x) = \sqrt{2x + 8} \)[/tex] at [tex]\( x = 4 \)[/tex], follow these steps:

1. Substitute [tex]\( x = 4 \)[/tex] into the function:
[tex]\[ g(4) = \sqrt{2 \cdot 4 + 8} \][/tex]

2. Simplify the expression inside the square root:
[tex]\[ 2 \cdot 4 = 8 \][/tex]
So,
[tex]\[ g(4) = \sqrt{8 + 8} \][/tex]

3. Add the constants inside the square root:
[tex]\[ 8 + 8 = 16 \][/tex]
Therefore,
[tex]\[ g(4) = \sqrt{16} \][/tex]

4. Evaluate the square root:
[tex]\[ \sqrt{16} = 4 \][/tex]

So, the value of [tex]\( g(4) \)[/tex] is [tex]\( 4.0 \)[/tex].
