Using a piece-wise function, the representation of the graph is given as follows:
Walking uphill for 3 hours and downhill for 1 hour.
<h3>What is a piece-wise function?</h3>
A piece-wise function is a function that has multiple definitions, depending on the input.
In this problem, we have that:
- For the first 3 hours, the slope is of 2 miles per hour, equivalent to walking uphill.
- For the final hour, the slope is of 3 miles per hour, equivalent to walking downhill.
Hence the meaning of the graph is:
Walking uphill for 3 hours and downhill for 1 hour.

Find A, B and C
Rearrange the expression
To do this, we simply compare the expressions on both sides of the equation.
So, we have:
--- (1)
--- (2)
--- (3)
Divide both sides by x² in (1)
Divide both sides by x in (2)
Substitute 2 for A.
Make B the subject
Substitute 2 for A and -1 for B in (3)
Make C the subject
