  2. 2. <ul><li>An equation that models sound intensity is </li></ul><ul><li>dependent on what two variables? </li></ul><ul><li>a)    time and altitude </li></ul><ul><li>b)    frequency and wavelength </li></ul><ul><li>c)    time and frequency </li></ul><ul><li>d)    wavelength and amplitude </li></ul>
  3. 3. <ul><li>Notes sound good together if their combined waveform is: </li></ul><ul><li>a)    Regular and repeating </li></ul><ul><li>b)    Irregular and random   </li></ul>
  4. 4. <ul><li>The height versus time equation of a skier moving down a hill is shown below. </li></ul><ul><li>120(0.5^(0.1*x))+2*sin(x) </li></ul><ul><li>What two types of functions could be combined to create this graph?   </li></ul>
  5. 5. <ul><li>     Which of the following situations would not be best represented by a combined function: </li></ul><ul><li>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 </li></ul>
  6. 6. <ul><li>Let f(x)=(x 2 ), let g(x)=(x+6). </li></ul><ul><li>Using this information, determine the composite function of y=f(g(x)) </li></ul>
