g(a) =

Answer 1

Evaluating Functions

When we're asked to solve for
`f(x)` when x is replaced with a number, we can replace every x in the equation with that number, and simplify.

Solving the Question

We're given:

`g(x) = 8x + 7`

⇒ To find g(a), replace x with a:

`g(a) = 8a + 7`

⇒ This cannot be simplified any further, so this is our final answer.

Answer

`g(a) = 8a + 7`
