Two questions:

1. exponential functions such as y=b^x are defined by only b > 0. why would you not want to use negative values of b?

2. can you consider y=1^x or y=0^x to be exponential functions? how are they different from other exponential functions?

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
