March 19 Quadratic Test Review

  1. 1. 2 f(x) = 2x - 4x - 1 Find the: vertex axis of symmetry domain range roots / zeros / x-intercepts y intercept GRAPH IT!
  2. 2. 2 f(x) = 2x - 4x - 1 vertex
  3. 3. 2 f(x) = 2x - 4x - 1 axis of symmetry x=1
  4. 4. 2 f(x) = 2x - 4x - 1 domain (- , ) 8 8
  5. 5. 2 f(x) = 2x - 4x - 1 range [-3, ) 8
  6. 6. 2 f(x) = 2x - 4x - 1 y-intercept y-intercept = -1
  7. 7. f(x) = 2x 2 - 4x - 1 zeros / roots / x-intercepts 0 = 2x 2 - 4x - 1 2 x = -b ± √b - 4ac 2a x = 4 ± √24 4
  8. 8. x = 4 ± √6*4 4 x = 4 ± 2√6 4 x = 1 ± 0.5√6
  9. 9. f(x) = 2x 2 - 4x - 1
