Question

Select the correct answer.

For what value of g does the function

`f(g) = {g}^(2) + 3g`
equal 18?

Answer 1

g=3

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.
