How to graph an exponential function An exponential function of the form that was specified above will have a characteristic exponential shape, and its general form will depend on whether the rate \(r\) is positive or negative. For a positive rate \(r\) we will haveexponential growth, and...
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...
An exponential function is a function with the general form f(x) = y = abx and the following conditions:x (input value) is a real number a is a constant and a is not equal to zero (a ≠ 0) b is bigger than zero (b > 0)...
To determine the points on the Y-Axis, we use the Exponent of the base of the exponential function. For example, let us graph the function f(x)= 2^x, where the base of this function is 2 and the Exponent is 'x'. When the Exponent of the base is equal to -1, then Y=1/2,...

Topics covered include the need for allowing students to sketch their own graph as well as identify where the graphs intersect. Also mentioned is the need for encouraging students to use ca...
Given three functions w(x), x(x), and y(x). The graph of w(x) is a cosine curve. The graph of x(x) is an exponential decay function. The graph of y(x) is a linear function with a positive y-intercept. Which function has a period?
