# Introduction to Transformations of Functions

This is part of the HSC Mathematics Advanced course under the topic Functions and sub-part Graphing Techniques, introduction to transformations of functions. In this post, we apply transformations to sketch functions of the form y=kf(a(x+b))+c ,  where f(x) is a polynomial, reciprocal, absolute value, exponential or logarithmic function and a,b,c and k are constants:

• Examine translations and the graphs of y=f(x)+c and y=f(x+b) using technology
• Examine dilations and the graphs of y=kf(x) and y=f(ax) using technology
• Recognise that the order in which transformations are applied is important in the construction of the resulting function or graph

In this video, we will understand how functions can be transformed and stretched horizontally and vertically, and reflected over the x-axis and y-axis.
