    \(\bf {\color{blue}{ f(x)}}=0.01(2)^{\color{red}{ x}}\qquad \qquad slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ y_2}}-{\color{blue}{ y_1}}}{{\color{red}{ x_2}}-{\color{red}{ x_1}}}\qquad thus \\ \quad \\ \cfrac{{\color{blue}{ f(15)}}-{\color{blue}{ f(12)}}}{{\color{red}{ 15}}-{\color{red}{ 12}}}\impliedby \textit{rate of change}\)

    well, the numerator is not 3, so.. check your functions again

    15-12 over 15-12 so it would be 3 right

    that's the denominator, yes, you'd need to get the numerator, and simplify the rational

    notice the function, the function is f(x), x turns to 12, solve it x turns to 15, solve that, subtract one from the other
