Graphing Exponential Functions: Useful Patterns

| No TrackBacks

Graphs are a great way to learn more about a function. It's not too difficult to create a graph based upon a function, as you just need to plug in numbers for X and solve the function to determine the points that create the graph. You might notice in the examples, the function never crosses the x-axis; instead it gets closer and closer without ever touching. It's impossible for the function to be negative and this results in graph that has a horizontal asymptote. Professor Edward Burger notes that exponential functions are easily recognized by their graph. No matter how you change the function, as long as it's exponential it'll always result in an asymptote, the big difference being the pitch of the curve and its location on the coordinate plane.
