Vertical line test
Explain the vertical line test
No vertical line can intersect the curve more than once
What are even functions symmetric with
Y-axis
What are odd functions symmetric with
origin
What are poles
limit/bounds of the function - bottom of fraction
What are one-to-one functions
Have a unique value of y for every value of x - passes horizontal line test
