In algebra there is a group of commonly used functions called parent functions and most graphs are either transformation of these functions or a combination of them.
They are:
- y = x2 called the quadratic or square function
- y = x3 called the cubic function
- y = x called the linear or identity function
- y = |x| called the absolute value function
- y = √x called the square root function ( this can also be written x½)
- y = ∛x called the cube root function ( this can also be written x⅓)
Lets work with the cubic function y = x3 The graph of the cubic function is:
How do we move the graph down 2 units?
