Which kind of function best models the set of data points (–1, 22), (0, 6), (1, –10), (2, –26), and (3, –42)?

LINEAR. I arrived at that conclusion after solving for the slope.

m = y1 - y2 / x1 - x2 
m = 22 - 6 / -1 - 0 = 16/-1 = -16
m = 6 - (-10) / 0 - 1 = 16/-1 = -16
m = -10 - (-26) / 1 -2  = 16/-1 = -16

Which kind of function best models the set of data points (–3, 18), (–2, 6), (–1, 2), (0, 11), and (1, 27)? NONE OF THE ABOVE

3. What function can be used to model data pairs that have a common ratio? EXPONENTIAL
