PLEASE HELP!! Parents wish to have 90,000$ available for a child's education. If the child is now 3 years old, how much money must be set aside at 5% compounded semiannually to meet their financial goal when the child is 18?

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
