The Graphs of Exponential functions can be easily sketched by using three points on the X-Axis and three points on the Y-Axis. The points on the X-Axis are, X=-1, X=0, and X=1. To determine the points on the Y-Axis, we use the Exponent of the base of the Exponential function. If the Base of the Exponential is the number 'b', where b > 0 and b ≠ 1, then the points on the Y-Axis, that corresponds respectively with the points on the X-Axis, are; y=b^x,where, x=-1, and x=0, and x=1.The coordinates of the points that the graph would pass through are(-1,1/b),(0,1) and (1,b). When working with these points, the graphs can be easily sketched.

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, since 2^(-1) = 1/2. When the Exponent of the base is 0, any b to the Exponent 0, is equal to 1, then Y=1, since 2^0 = 1 . If the Exponent of the base is 1, then y=2, since 2^1 = 2. The coordinates of the points that this graph would pass through are (-1,1/2),(0,1) and (1,2).
