Find a particular value of f(x)
In this lesson, we will use substitution skills and knowledge of order of operations to find a particular value of f(x)
Unit Overview: Functions

Solve equations using f(x) =
In this lesson, we will use knowledge of using inverse functions to solve equations using f(x)
Composite functions
In this lesson, we will apply more than one function to a number or a variable using substitution, knowledge of expanding brackets and also apply these skills to solving equations such as fg(x) = h(x)
Find inverse functions
In this lesson, we will use knowledge of using inverse functions (function machines) and making x the subject to find inverse functions.
