Notes sound good together if their combined waveform is: <br />a) Regular and repeating<br />b) Irregular and random <br />
The height versus time equation of a skier moving down a hill is shown below.<br />120(0.5^(0.1*x))+2*sin(x)<br />What two types of functions could be combined to create this graph? <br />
Which of the following situations would not be best represented by a combined function:<br />a) path of a bungee jumperb) acceleration of a falling object due to gravityc) a predator-prey relationshipd) motion of interfering waves<br />
Let f(x)=(x2), let g(x)=(x+6).<br />Using this information, determine the composite function of y=f(g(x))<br />
If you combine these graphs what would the resultant graph look like?<br />

When modelling combined functions, you need a minimum of 1 or 2 or 3 or 4 functions?<br />
(x+1)2/ x 2 +3x+4 can be simplified to:<br />a) (x+1) / (x+3)<br />b) (x+1) / (x+2) <br />c) (x+3) / (x+1) <br />d) (x+2) / (x+3)<br />

If your heart rate usually looks like this:<br /> Explain what would happen if you got<br /> scared: <br /> a)the frequency would increase and the heart beats would get closer together <br />b)the frequency would decrease and the heart beats would get farther apart <br />c)the maximums would get higher and the minimums would get lower <br />d)it would not make as periodic a function <br />
