Question

Select the correct answer.

For what value of g does the function
$f(g) = {g}^{2} + 3g$
equal 18?

Answer 1

Answer:

g=3

Step-by-step explanation:

f(g)=g²+3g

Personally, I would do a guess and check to figure this out.

Let's try a number like 3. Insert it -

f(3)=3²+3(3) =9+9=18

Therefore, the answer is 3.
