Question

1. Which kind of function best models the set of data points (-1, 22), (0,6), (1,-10), (2,-26),

and (3, 42)
(1 poin
linear
quadratic
exponential
none of the above

Answer 1

You can clearly check, by plotting them, that the points don't lie on a line.

Moreover, they present a descending pattern, until the last point, which comes back up.

This kind of behaviour (descendent and then ascendant) can be modelled by quadratic functions (parabolas)

Answer 2

I believe that the last point is supposed to be (3, -42) rather than (3, 42). So, when graphing these points, the function that best represents the set of data points would be a linear function.

**As for the rest of the questions:

1. A) linear

2. D) none of the above

3. C) exponential

4. B) a = 25g + 100
