From Table to Formula
Wait for the applet to completely load, then click on Problem 1.

Problem 1   Problem 2   Problem 3   Problem 4   Problem 5  

The animation shows a picture of an accelerating object, i.e. a motion that is modelled by a quadratic function. The table shows the position of the object (x in metres) every second. For each problem:
1. Draw a graph of x against time.
2. Find an algebraic formula modelling the situation.
3. Find x if t = 12.
Reflect on similarities across the problems - what are the characteristic features of the tables, of the graphs and of the formulas for all these problems?

In Problem 1, what is x(12)?    

In Problem 3, what is x(12)?    

In Problem 4, what is x(12)?
