Function an Inverse
Grad 12 Note
Verticle line test
If vertical lines cuts the graph once then its a function
Anything more then its not a function
To restrict a ‘non graph’ you can either say
- X≤0
- X≥0
This is to restrict on of the parabolas arms
Similar to log graphs where you swap x and y
But it’s just solve-able
