  1. Ch. 9 Day 1 TLW: 2A.4A Graph Parent Functions 2A.9C, 2A.10C Find domain, range, intercepts, and asymptotes

  2. Go over HW 9.0 … you MUST be able to graph these parents and their shifts!!!

  3. Notes 9.1 How to Find Asymptotesin reciprocal functions Horizontal Asymptote: If Exponent is: Asymptote is: Y=0 BOB0 Y=___ BOTN DNE Divide Coefficients EATS DC Vertical Asymptote: Simplify Function and set denominator equal to zero and solve for x

  4. -.5 -1 H. Asymptote: V. Asymptote: und BOBO 1 Y=0 .5 Set denominator equal to 0 X=0

  5. Find asymptotes and equations H. Asymptote: V. Asymptote: EATS DC y = 3 Set denominator equal to 0 4.5 X = -4 6 und 0 1.5

  6. with asymptotes: and Write and graph a translation of What is the new equation? -1 0 und -4 -3

  7. Use synthetic Division 1 2 -3 -5 6 Check max/min on calc One root is 1. Find 2 others. 2 -1 -6 0 -6 -1 2 Solve the quadratic equation: -1.5 1 2 Degree 3 so opposite end behavior Positive 2 so end behavior up

  8. Find the intercepts and graph Positive 5 so end behavior up -b/2a finds x-coord of vertex Solve the quadratic equation: Degree 2 so same end behavior -1 1 -2 -3 Check min on calc min (-1.4,-12.8)

  9. HW: WS 9.1 Due next class! Quiz #1 next class
