a. For a graph to be a function, it must pass the vertical line test. The vertical line test is a test you do by drawing vertical lines through the graph and checking to see if, at any point, the line cuts the graph more than once, if it does cut the graph more than once, then the graph isn't a function Eg.|dw:1443505429946:dw|

b. The domain is the range of x co-ordinates on a graph so for eg.|dw:1443505650004:dw| the domain of this graph is -3 <= x <= 5

c. The range, describes all the y coordinates that make up a certain graph, so for e.g. |dw:1443505842409:dw| The range here would be -4 <= y <= 4

you know your stuff really well. I have done that vretical line test about ten times and still felt confused.
FireKat97
  • FireKat97
with the vertical line test, if its failed at any point, the graph is not considered a function, even if it fails at one point alone

Just imagine cutting the graph at numerous spots, and if at any spot, its cut more than once, its no loner a function, its just a matter of practice really
