How can you tell if a graph is a continuous function or a discrete function?
The graph of a continuous function will not have any 'breaks' or 'gaps' in it. You can draw it without lifting your pencil or pen. The graph of a discrete function will just be a set of lines.
What is a way of determining whether a graph is a function?
For a graph to be a function, each x-value has to take maximum one y-value. One way you can check this is drawing a vertical lines through points on the graph. If a single vertical line intersects the graph in more than one place, that means the x-value defining the line has more than one y-value, and the graph is not a function.tl;dr: Draw vertical lines through the function, and if the lines only intersect the graph once, you have a function.
What is the different shape a relation from a function?
When graphed, a function has any shape so that all vertical lines will cross the graph in at most one point. A relation does not have this condition. One or more vertical lines may (not must) pass thru a relation in more points.
Create rational function that has the given lines as asympotes?
y=o, x=-3,x=0 and x=2
How do you type a y with two lines?
|y| If this is what you meant, it is the top function of the key with the back slash, which is directly to the right of the key with the brackets.
