F (x) = p (x)/q (x) where p (x) and q (x) are polynomials and q (x) ≠ 0. A rational function is of the form. How do you find the horizontal asymptote if x is multiplied to a higher degree in the denominator than in the numerator? Holes (removable discontinuities) factor numerator & denominator simplify if anything cancels, then there is a hole (more than one factor cancels more than one hole) 15 • = 3 5 = 3 65 13 • 5 13 + 4 x 12 = 4( x + 3) 4 x 2 = − 2 x − 15 ( x − 5)( x + 3) x − 5.

Graphing reciprocal linear and quadratic functions, quotients of linear functions, combinations of functions, solving rational equations and inequalities. 1) f (x) = − 4 x Let f ( x) = a x n + b x 2 + 10 c x m + d x − 2 , where m and n are integers and a , b , c and d are unknown constants. Holes (removable discontinuities) factor numerator & denominator simplify if anything cancels, then there is a hole (more than one factor cancels more than one hole)
