So, in all, I'm really just asking how I would use log in general. (Please answer in a 'for dummies' format please! :) Not exactly the best with the vocabulary!) Due to some research, I've learned...

On a graph, graph the function f(x)=a^x and g(x)=log sub a x when a=2, a=.5 and a=1. how many points of intersection does each value of a produce ?

Create a formula then find the temp of the pie after 120 minuites

what would the exponential regression question be that models the number of grams remaining? y, after x number of days

I don't know the transformations neither do I know which one will give me a y-intercept

For every half life how many # of days and grams remaining?
