2. to strengthen the "exponential function" concept. The concept to guide students to integrate the index to summed up the definition of exponential function, and points out that the form of exponential function to the students, please students thinking about whether to restrict the base fo...
Step Three: Evaluate the function for each value of x. “Evaluate” means to plug the x-values into the equation and solve. x f(x) -2 3-2 = 1/32 = 1/9 -1 1/3 0 1 1 3 2 9 The points in our chart are then plotted on the x-axis and y-axis of our graph giving us th...

Example 4 AGAIN:(easier)Find an exponential function of the formf(x)= abxwhich will pass through the points (-3,256) and (2, ¼).Round to nearest hundredths if needed. We will solve this again, using theexponential regressioncapabilities of the graphing calculator. ...
The easiest base to picture is 2, so we will look at the function 2x. For each value ofx, this guy spits out the value of 2 raised to that power. Using our rules above, its easy to calculate this forxan integer; you just start with 1 (which is 20) and double it to get 21, ...
Many processes can be modeled using the exponential function since it is the solution to a number of differential equations. The simplest of these are dx/dt = ax and dx/dt = −ax.4 The solutions to these equations are xo eat and xo e−at, respectively, where xo is the value of ...
