On the other hand, graphs of exponential decay functions will have a left tail that increases without bound and a right tail that gets really close to the x-axis. Points can be generated with a table of values
Learn how to graph exponential functions. Discover the general form of exponential functions. Explore how to write an exponential function and see...
In this expression, the parts of an exponential function are the positive base b≠1, the initial value a≠0 (which corresponds to the y-intercept on a graph), and the independent variable as the exponent. When looking at any exponential function equation, we also have to pay attention to...
If there is exponential decay, as shown in the figure on the right, the graph will curve downward. A real life example of exponential decay is radioactive decay. The graph crosses the y-axis, but not the x-axis. Properties of the exponential functionIf y = abx, a > 0 b > 0, the...

The article discusses an effective way of teaching the graph of exponential function and its inverse graph. Topics covered include the need for allowing students to sketch their own graph as well as identify...
These increases (or decreases when working with negative exponents) are consistent over a definite period of time as a function of the variable x. For example, the increases are consistently double or triple. The rapid increases characteristic of exponential functions can be seen on the graph ...

and graph the function [Fig. 3(b)]. The points on the graph of f (x) for x 0 are indistinguishable from the x axis in Figure 3(b). However, from the properties of an exponential function, we know that f (x) 0 for all real numbers x and that 1 2 E X A M P L E 1 x...
This is the general Exponential Function (see below for ex): f(x) = ax ais any value greater than 0 Properties depend on value of "a" Whena=1, the graph is a horizontal line aty=1 Apart from that there are two cases to look at: ...
