How to graph Cubic and Exponential Functions
In this section I will explain to you how to graph cubic and exponential functions. First of all we need to make sure we understand what cubic and exponential functions are. A cubic function is a function in which the highest power of x is three. f(x) = 2x^3 + 4x^2  7 is an example of a cubic function. An exponential function is a function where x is in the exponent of a term. g(x) = 5^x + 2 is an example of an exponential function for x is in the exponent. Study all the following videos during your maths revision if you want to pass your IGCSE GCSE Maths exam. I will explain to you what the graphs of cubic and exponential functions look like. In each video I will explain something new you need to know. Have fun!
