Answer:
Define:
Domain is the set of values that you can input in a function
Range is the set of values that corresponds to the output of a function, the set of values corresponding to its results
The vertical line test is a simple test you can do with a graph to know if this graph correspond to a function or not: you have to draw a vertical line, parallel to the y-axis and if that line touch the graph in just one point, it is a function
What is the domain and range of each function?
Domain = {3, 5, 7, 8, 11}
Range = {6, 7, 9, 14}
Is each relation a function?
Yes
