  1. AAT 1/7-8 Unit 3, Lesson 3, Inv 1

  2. Warm Up • ½ sheet of paper when you walked in! • First 15 minutes! 

  3. Solving for Maximum Value (p.209) Reasoning: • Distributive Property • The function gives height, height is zero when gymnast is on the trampoline 3. Substitution substitute the factored form for h(t)

  4. Solving for Max Value Continued Reasoning: • Zero product rule (product is zero when one of the factors is zero) • Multiplication and Addition properties of equality (solve for t) • Parabolas have an axis of symmetry – the maximum value should be the midpoint between t=0 and t=1.5 7. Translation of function notation into words

  5. Zeros: x = 0 or (x-5) = 0 x=0, x=5 f(x) =x(x-5) Find the zeros – or find all x for which f(x) = 0 Sketch a graph Produce the graph on a calculator

  6. Group Work Find the zeros – or find all x for which f(x) = 0 Sketch a graph Produce the graph on a calculator • #2 DO: b – h • #3 a-e (p. 210) • Follow the same steps but now you will have three zeros

  7. Write the equation from zeros Zeros: f(4) = 0, f(1) = 0 Equation: f(x) = (x )(x ) (x ) = 0 when x=4 (x ) = 0 when x=1 (x – 4) = 0 when x=4 (x – 1) = 0 when x=1 f(x) = (x – 4 )(x – 1)
