Question

State if each graph is continuous or discrete. then State whether it is a function​

Answer 1

Step-by-step explanation:

Discrete data can only have certain values.  For example, if you roll a die, there are only 6 numbers you can get.  Continuous data can have any value within a range.

Graphically, discrete data will appear as only points, where as continuous data appears as a line or curve.

So the top left and bottom right graphs are discrete.  The top right and bottom left graphs are continuous.

To be a function, each x value can only have 1 y value.  Graphically, we can check this using the "vertical line method".  Imagine a vertical line (or use a ruler or straight edge) and move it from left to right.  If it ever crosses the graph in two or more places, the graph is not a function.

Therefore, the graphs on the left are not functions, and the graphs on the right are functions.
