Transform our data so that it allows a linear model. We can find the formula of an exponential function by using two points on the curve, substituting them into the formula y = abx, and solving the system of two equations in two unknowns. If you know two points that fall on a particular exponential curve, you can define the curve by solving the general exponential function using those points. If we are given the graph for an exponential function, we can just pick any two points on the curve. Its surface has many folds, giving it a wrinkled appearance.
