If we know two points, we can write and exponential function that contains them by solving for "a" and "b" in y=ab^x . The first x,y pair will be used to write an expression for "a" in terms of "b," and the second x,y pair will be used along with that expression to solve for b. Always check your work by substituting each original point into what you think the function should be.
