Question

Does this graph represent a function? What is the domain and range of the graph?

Answer 1

Answer:

Yes; domain: all real numbers; range: y $\geq$ 0

Step-by-step explanation:

1. Use the vertical line test to see if it is a function.

2. Figure out what the lowest and highest point x can be. In this case x can be any number

3. Figure out what the lowest and highest point of y can be. In this case y is not negative, the lowest it can be is 0. So y $\geq$ 0

*Note: Domain are the x values & Range are the y values
