Today (one laptop per pair)

You can determine the period, equilibrium line and amplitude for a given periodic graph.

You are able to draw the graph of a periodic relationship given the period, equilibrium line, amplitude and a point it passes through. 

How are you doing today?

Calculate the equilibrium of this graph.

Calculate the amplitude of this graph.

State the period of this graph.

You might want to do a sketch for this question.
The graph of a periodic relationship has period 12, equilibrium 1 and amplitude 5. The graph passes through (6, -4).
The graph also passes through (36, a). Give the value of a, explain your reasoning.
