Henochmath walks us through an easy example to clarify this procedure. You can substitute this value for b in either equation to get a. At Wyzant, connect with algebra tutors and math tutors nearby. In his example, he chose the pair of points 2, 3 and 4, Plugging this value, along with those of the second point, into the general exponential equation produces 6.
In this form, the math looks a little complicated, but it looks less so after you have done a few examples. Variables Any lowercase letter may be used as a variable. For example, solving the equation for the points 0, 2 and 2, 4 yields: Why Exponential Functions Are Important Many important systems follow exponential patterns of growth and decay.

From a Pair of Points to a Graph Any point on a two-dimensional graph can be represented by two numbers, which are usually written in the in the form x, ywhere x defines the horizontal distance from the origin and y represents the vertical distance. The procedure is easier if the x-value for one of the points is 0, which means the point is on the y-axis.
By taking data and plotting a curve, scientists are in a better position to make predictions.
Although it takes more than a slide rule to do it, scientists can use this equation to project future population numbers to help politicians in the present to create appropriate policies. Exponents may not currently be placed on numbers, brackets, or parentheses.

Then it will attempt to solve the equation by using one or more of the following: If neither point has a zero x-value, the process for solving for x and y is a tad more complicated. For example, the number of bacteria in a colony usually increases exponentially, and ambient radiation in the atmosphere following a nuclear event usually decreases exponentially.
