Reading the title will take longer than watching the video! However, if you're wanting to know how to find the rule of a graph then this is the video for you.
This video takes a look at three common forms of equations; exponential and logarithmic functions. I look at what we need to know to solve these equations and, primarily, it's two coordinate values.
Knowing at least two coordinates allows me to use all sorts of algebra or my CAS to find the missing values.
Three examples are covered in the video and a number of top tips to help you ace the exam.
