    these are the answer choices: 1. f(x) has the highest value in 3 years; g(x) has the highest value in 10 years 2. g(x) has the highest value in 3 years; f(x) has the highest value in 10 years 3. f(x) has the highest value in 3 years; f(x) has the highest value in 10 years 4.g(x) has the highest value in 3 years; g(x) has the highest value in 10 years

    x is the number of years, right? so first, find f(x) when x = 3 and g(x) when x = 3

    Set the x to be 3 years and 10 years and see if either of them turns out greater than the other.

    g(x)=150(1.03)^x = 150(1.03)^3 = ?

    For 3 years f(x)=5x+150=165 for the first one g(x)=150(1.03)^3=163.90

    no, please look at f(x) and g(x) again...

    Yeah vocaloid would tell you to do f(x)=5(10)+150=200 g(x)=150(1.03)^10=201.5
