Answer:
The value of g(a) is:
- g(a) = 3 - 2a
Step-by-step explanation:
Given
As the function g(x) is given by
To determine
g(a) = ?
In order to determine g(a),
substitute x = a in the function g(x) = 3 - 2x
g(x) = 3 - 2x
g(a) = 3 - 2(a)
g(a) = 3 - 2a
Therefore, the value of g(a) is:
- g(a) = 3 - 2a
