Understanding Contextual Graphs: Distance, Velocity, and Financial Graphs

The video tutorial covers three main types of graphs: distance-time, velocity-time, and financial graphs. It explains how distance-time graphs record an object's journey and how the gradient represents speed. For velocity-time graphs, the gradient indicates acceleration, and the area under the graph shows the distance traveled. Financial graphs are used for currency conversions and cost comparisons, with examples provided for understanding conversion rates and comparing costs.

Explain how financial graphs can be used for currency conversions.

Describe how to use a graph for cost comparisons between two services.
