Question

Evaluate g(3) if g(x) = 2x + 1.

Answer 1

Answer:

Value of $g(3) = 7$

Step-by-step explanation:

Given the function:

$g(x) = 2x+1$          .....[1]

we have to find the value of g(3)

Substitute x = 3 in [1] we have;

$g(3) = 2(3)+1$

⇒$g(3) =6+1$

Simplify:

g(3) = 7

Therefore, the value of g(3) is, 7

Answer 2

This problem asks, as simply put, the value of the function at x=3. So, plug in three to find your answer:

2(3) + 1 = 7, so g(3) is 7
