How to write an equation for an exponential graph

Then as the values of x increase, the slope becomes steeper and steeper. This is a typical line shape for an exponential graph. It gets very hard to plot the values accurately because they are so small — for instance is 0. For instance, is

How to write an equation for an exponential graph

Due to the nature of the mathematics on this site it is best views in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu items will be cut off due to the narrow screen width.

However, despite these differences these functions evaluate in exactly the same way as those that we are used to. We will see some examples of exponential functions shortly. We will be able to get most of the properties of exponential functions from these graphs.

Function evaluation with exponential functions works in exactly the same manner that all function evaluation has worked to this point. We will hold off discussing the final property for a couple of sections where we will actually be using it.

As a final topic in this section we need to discuss a special exponential function. In fact this is so special that for many people this is THE exponential function. Also note that e is not a terminating decimal.

This special exponential function is very important and arises naturally in many areas.

As noted above, this function arises so often that many people will think of this function if you talk about exponential functions. We will see some of the applications of this function in the final section of this chapter.Writing Exponential Equations.

a. Write an exponential function of the form y = abx that could be used to model the world population y in billions for to Write the equation in terms of x, the number of years since (Round the value of b to the nearest ten -thousandth.) b.

Suppose the population continued to grow at that rate.

Estimate the population in c. An exponential function is a function that contains a variable exponent. For example, f (x) = 2 x and g (x) = 5ƒ3 x are exponential functions. We can graph exponential functions. Jan 03,  · So the equation for that function is y = 6^x.

The other coordinate (0,1) is useless since all exponential functions pass through (0,1) since anything to the power of 0 is 1. Any question that asks you for the equation of an exponential function, you ALWAYS find (1,b).Status: Resolved. This calculator will calculate the exponential function with the given base and exponent.
