8-3Rational Functions Unit Objectives: Graph a rational function Simplify rational expressions. Solve a rational functions Apply rational functions to real-world problems Today’s Objective: I can graph a rational function.
Rational Function: and are polynomials • Hole • Asymptote Continuous Graph: No breaks in graph • Discontinuous Graph: • Breaks in graph
Discontinuities: • Where the Denominator = zero Domain: • All real numbers (except discontinuities Vertical Asymptotes: Non-removable Holes: Removable Same factor in numerator and denominator Discontinuity: or or Domain: All reals but All reals but Holes: V. Asymp:
Horizontal Asymptotes: • Leading term of numerator and denominator (standard form) No horizontal asymptote No horizontal asymptote Range: All real numbers except horizontal asymptote & holes
Graph: Find and graph asymptotes & holes Find and graph additional points → each side of v. asymptote Sketch graph • Discontinuities: Hole: • None V. Asymp.: H. Asymp.: Domain: Range:
Graph: • Discontinuities: Hole: V. Asymp.: Domain: Range: H. Asymp.:
Graph: Discontinuities: Hole: V. Asymp.: H. Asymp.: Pg. 521 #13-31 odds Domain: Range:
