  • 1. By: Cindel, Sarah, Lucas, Aleks, Quinn and Olivia
  • 2.
    • An equation that models sound intensity is
    • dependent on what two variables?
    • a)    time and altitude
    • b)    frequency and wavelength
    • c)    time and frequency
    • d)    wavelength and amplitude
  • 3.
    • Notes sound good together if their combined waveform is:
    • a)    Regular and repeating
    • b)    Irregular and random  
  • 4.
    • The height versus time equation of a skier moving down a hill is shown below.
    • 120(0.5^(0.1*x))+2*sin(x)
    • What two types of functions could be combined to create this graph?  
  • 5.
    •      Which of the following situations would not be best represented by a combined function:
    • a)    path of a bungee jumper b)    acceleration of a falling object due to gravity c)    a predator-prey relationship d)    motion of interfering waves
  • 6.
    • Let f(x)=(x 2 ), let g(x)=(x+6).
    • Using this information, determine the composite function of y=f(g(x))
  • 7.
    • If you combine these graphs what would the resultant graph look like?
  • 8.
    • Which musical note has the higher frequency: C or C#?
    •    
  • 9.
    • When modelling combined functions, you need a minimum of 1 or 2 or 3 or 4 functions?
  • 10.
    • (x+1) 2 / x 2 +4x+3 can be simplified to:
    • a) (x+1) / (x+3)
    • b) (x+1) / (x+2)
    • c) (x+3) / (x+1)
    • d) (x+2) / (x+3)
  • 11.
    • If f(x)=x+4 and g(x)=x2+1, then f(x)+g(x)=?
    • a) x 2 +x+5
    • b) x+5
    • c) x 2 +3
    • d) 2x+5
    • e) x 2 +x+7
  • 12.
    • If your heart rate usually looks like this:
    • Explain what would happen if you got
    • scared:
    • a)the frequency would increase and the heart beats would get closer together
    • b)the frequency would decrease and the heart beats would get farther apart
    • c)the maximums would get higher and the minimums would get lower
    • d)it would not make as periodic a function
