then switch the x and y

x and y intercepts

For the y-intercept set
x=0 and solve

For the x-intercept set
y=0 and solve

Asymptotes

Where the function
approaches but never
touches

Domain and Range

Where is the function
continuous

Is it a function or not?

ex. when the denomiator
of a function equals zero
