Question

Which exponential function has an initial value of 2? f(x) = 2(3x) f(x) = 3(2x)

Answer 1

f(x) = 2(3x)
Exponential functions represent the initial value outside of the parentheses so if 2 is the initial value it has to be on the outside of the parentheses. 
Exponential growth formula.
$y=a(1+r)^{x}$
a represents the initial value.

Answer 2

The answer is f(x)=2(3x) I just took the quiz
