Days when the forecast temperature the same as the actual temperature are:

For an experiment in Botany, two different plants, plant A and plant B were grown under similar laboratory conditions. Their heights were measured at the end of each week for 3 weeks. The results are shown by the following graph.
How much did Plant A grow during the 3rd week?

What was the minimum actual temperature during the week?

The actual temperature differs the most from the forecast temperature on:

How far is the place of the merchant from the town?

Value of $$y$$ increases exponentially from $$y=-4$$ to $$y= +4$$, then plot a $$x-y$$ graph for the given constraint.

Which is the highest peak?
