Best ResponseYou've already chosen the best response.2the function is this? \[\LARGE f(x) = 0.01(2)^x\]

Best ResponseYou've already chosen the best response.0im not even sure how to find the function values.. i get all mixed up when it comes to trying to find the answers to these type of questions.

Best ResponseYou've already chosen the best response.2what you do is replace every x value with the input in question so say you wanted to find f(2) replace every x with 2 \[\LARGE f(\color{red}{x}) = 0.01(2)^\color{red}{x}\] \[\LARGE f(\color{red}{2}) = 0.01(2)^\color{red}{2}\] \[\LARGE f(2) = ???\]

Best ResponseYou've already chosen the best response.2at this point, you use a calculator to compute `0.01*(2)^2` you can use this calculator if you don't have one http://web2.0calc.com/

Best ResponseYou've already chosen the best response.2did you type in `0.01*(2)^10` ?

Best ResponseYou've already chosen the best response.0i got 10.24 this time.. i made a mistake

Best ResponseYou've already chosen the best response.2now you compute \[\large \frac{f(b)f(a)}{ba} = \frac{f(10)f(2)}{102} = \frac{10.24  0.04}{102} = ??\]
