When sketching inverse functions we can use both the original graph and equation to determine what the inverse function will look like.
This is part of the Preliminary Mathematics Extension 1 Syllabus from the topic Functions: Further, Work with Functions. In this post, we will explore Graphical relationships sketching square root functions.
Here we will learn to examine the relationship between the graph of = () and what happens when a square root is applied.
Key information to remember here is:
- The number inside a square root cannot be negative. This means that if there are negative y values, the graph will not exist there.
Let’s check out some videos on graphing square root functions.
