Tommy and Erin are building a skateboard ramp. They want the ramp to be 3 feet tall and 5 feet long. Tommy thinks that they can
use a piece of plywood that is 4 feet long to cover the top of the frame.
A)Why is Tommy's reasoning incorrect? Explain.
B) How long does the piece of plywood have to be to cover the top of the frame of the skateboard ramp? Show your work.
C) Erin’s parents bought a 10 foot piece of plywood for her and tommy to use to cover the top of the frame. Draw and label a ramp they could create. Justify your work using the Pythagorean Theorem.
Please answer all parts I really need the answer to these questions.

A piece-wise function combines more than one functions of different input values.
<em>The value of f(-1) is -3</em>
From the graph, we have the following observations
- <em>When x = -1, y = -3</em>
- <em>When x = -1, y = -4</em>
Notice that there is a closed circle at the point where x = -1 and y = -3.
This means that y = -3 is inclusive of the values of y on that particular function
However, there is an open circle at the point where x = -1 and y = -3.
This means that y = -4 is exclusive of the values of y on that particular function
The correct corresponding value of y is when y is inclusive.
Hence, the value of f(-1) is -3
