Plug in the first point into the formula y = abx to get your first equation. You can learn more about the domain of functions (and how to find it) here. Did you have an idea for improving this content? Divide both sides of Both these answers assume the form f(x) = ab^x; however, this presumes that the exponential function has an asymptote at x=0; it also assumes that base is important, but b can always be converted to e. Now you can also solve this problem with the more general f(x) = ae^x + c, which is still exponential, but now leaves the asymptote open to other possibilities and uses the natural base.
