1. Rational Functions Learning Objective: to find the domain and intercepts for rational functions Warm-up (IN) 1.Factor completely 2.Find the vertex, x- & y-intercepts, max or min, direction of opening and domain and range of

2. Notes! Rational Functions - a quotient of polynomials Like… where p(x) and q(x) are polynomials, the domain for the rational function is all real #s, except where q(x) = 0!! ~ set denominator equal to zero and solve!

3. Ex 1 - Find the domain and y-intercepts of the following function D: All real #s except 2 y-int Ex 2 - Find the domain and both the x- and y-intercepts of Remember ~ the denominator ≠ 0!! D: All real #s except -5 y-int x-int

4. D: All real #s except 2 y-int x-int D: All real #s except 4 and -3 y-int x-int

5. D: All real #s except -4 and -5 y-int x-int

6. HW – Rational Functions wksht Out – find the domain of Summary – Today I learned how to… Don’t forget about POW!!
