A power model is a type of function in the form y=a*x^b. Use the points (1,4), (2,8), (3,16), and (4,64) and a calculator to find an exponential model and a power model for the data. Then use each model to predict the values of y when x = 6. Graph the points and models in the same window. What do you notice?

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
