This may seem like a silly question, but I always have trouble with Rational Functions. Could someone explain a simple way of trying to find one? My math teacher puts things in complicated ways.

Question

ineedhelplz · Answer

A rational function is defined as the quotient of polynomials in which the denominator has a degree of at least 11. In other words, there must be a variable in the denominator

I understand that, I just don't understand how to graph them like they should be? Does that make sense?

ineedhelplz · Answer

Oh how to graph them?

nampa · Answer

Yeah. I don't really understand that part.

ineedhelplz · Answer

Steps involved in graphing rational functions:

Find the asymptotes of the rational function, if any.
Draw the asymptotes as dotted lines.
Find the x -intercept (s) and y -intercept of the rational function, if any.
Find the values of y for several different values of x .
Plot the points and draw a smooth curve to connect the points. Make sure that the graph does not cross the vertical asymptotes.

or do you want more of an explanation?

nampa · Answer

Would you need a graphing calculator for them, or is it easier to graph them by hand?

ineedhelplz · Answer

The graphs of the rational functions can be difficult to draw... Using a graphing calculator would be easier but If you don't have one on hand there are lots of free ones online!
