  • The rule for this pattern is: y = 3 × 2x (Power of x).
  • The rule for this pattern is: y = 0.4 × 3x. (Power of x)
    F The rule for this pattern is: y = 0.4 × 5x.
  • They are “linear”because if plotted they give a line. T/F
    True
  • The rule for this pattern is: y = x2 + 3x + 2.
    F The rule for this pattern is: y = x2 + 3x + 3.
  • y = 4x + 12.
    T
  • A = 0.5t + 5
    F A = 0.5t + 5.5
  • The rule for this pattern is: p = –0.5n2 + 1.5n + 10
    F The rule for this pattern is: p = –0.5n2 + 1.5n + 100.
  • The rule for this pattern is: p = 10n – 5 T/F
    T
  • The rule for this pattern is: y = 160 × 0.5x (Power of x)
    T
  • tn = n2 + n + 1. (2 is squared)
  • The rule for this pattern is: y = 2x – 1.T/F
    T
  • The rule for this pattern is: y = 3x + 1.T/F
    F The rule for this pattern is: y = 3x + 2.
  • They have equations of the form y = a x2 + b x + c. T/F
    T
  • d = 4p – 3
    T
  • The rule for this pattern is: y = 2x2 – 2x + 5.
  • b = –5a + 205
    T not + 200, because that’s not the value at a = 0
