Graph exponential functions and evaluate the results As we discussed in the previous section exponential functions are used for many real-world applications such as finance forensics computer science and most of the life sciences. I When a 1 a1 a 1 the graph strictly increases as x. F x ab x where a is a constant b is a positive real number that is not equal to 1 and x is the argument of the function.
56 56 5 6-6 50.
For real numbers c and d a function of the form is also an exponential function since it can be rewritten as. When given the graph of an exponential function we can also determine the expression for the graph by inspecting the points the curve pass through. It takes the form. Lets find out what the graph of the basic exponential function y a x yax y a x looks like.
