A function that is always linear

A function defined by the ratio of two polynomials

A function with no restrictions on its domain

A function that cannot be graphed

Because the numerator cannot be zero

Because the function must be linear

Because division by zero is undefined

Because the function must be quadratic

By setting the numerator equal to zero

By graphing the function

By setting the denominator equal to zero and solving

By finding the x-intercepts

All positive values

Values that make the numerator zero

Values that make the denominator zero

All negative values

A point where the graph crosses the x-axis

A line where the graph approaches but never touches

A line that the graph intersects at multiple points

A point where the graph crosses the y-axis
