The value of
.
Solution:
Given function:

Substitute x = –4 in g(x), we get


To make the denominator same, multiply and divide the 2nd term by 3.


It is given that, if x = –2, then g(x) = 3
Therefore g(–2) = 3
Substitute x = 2 in g(x), we get


To make the denominator same, multiply and divide the 2nd term by 3.
