Does this graph show a function? explain how you know.

ANSWER
Yes,the graph passes the vertical line test.
EXPLANATION
The graph above shows a function because if we draw a vertical line across the graph anywhere, it will never intersect the graph more than once.
This is what we call the vertical line test.
Since the graph of the function passes the vertical line test, the graph shows a function.
See graph
Therefore the correct answer is option C.

Answer:
<u>Given</u>
- Equation 5x - y = 12
and
- Inequality 5x - y > 12
<em>See the graphs attached</em>
To draw the graphs follow the rules we described in the previous questions.
- 1. Identify x-intercept and y-intercept and connect them to have the line.
- 2. Shade the region above or below the line for the inequality.
We see the only difference the expressions have is the equation or inequality symbols.
- Equation symbol means the graph of the equation is a line.
- Inequality symbol means the graph of this is a region above the same line, in our case the line is not a part of the covered region because it is "<".
We can state that the inequality excludes the line and includes only the region above the same line.
