For f(x) = 0.01(2)x, find the average rate of change from x = 12 to x = 15.

Answer 1

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

Answer 2

So 3? @jdoe0001

Answer 3

hmm what did you get for the numerator?

Answer 4

3

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

but how @jdoe0001

Answer 10

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

Answer 11

Oh so is the answer c?
