We can understand the process ofgraphingexponential function by taking some examples. Let us graph two functions f(x) = 2xand g(x) = (1/2)x. To graph each of these functions, we will construct a table of values with some random values of x, plot the points on the graph, connect t...
Graphing the Function The base number in an exponential function will always be a positive number other than 1. The first step will always be to evaluate an exponential function. In other words, insert the equation’s given values for variable x and then simplify. For example, we will take...
Before we begin graphing, it is helpful to review the behavior of exponential growth. Recall the table of values for a function of the form f(x)=bxf(x)=bx whose base is greater than one. We’ll use the function f(x)=2xf(x)=2x. Observe how the output values in the table below ...
