Question the-fu

The functions $f$ and $g$ are defined by the given equations, where $x\ge 0$. Which of the following equations displays, as a constant or coefficient, the maximum value of the function it defines, where $x\ge 0$?

1. $f\left(x\right)=33{\left(0.4\right)}^{x+3}$
2. $g\left(x\right)=33\left(0.16\right){\left(0.4\right)}^{x-2}$
