Question

Six Data Tables (**A, B, C, D, E, F**) are shown
below.

For each Table, decide which of two methods (**table
only** or **equation, graph, or
table**) can be used to represent the data.

For the purposes of this question, assume that we only know and
can use **two** graph forms / equations:

**x= c t + d (straight line graph)**
and **x = b t ^{2}+ c t + d (quadratic
curve graph)**.
