All Graphs That Represent A Function. Put x into the equation say 3 so y 2 3 6. The vertical line test can be used to determine whether a graph represents a function.
The graph shown here has 2 curves and one straight line. Give reason for your answers concerning each graph. The graph of the function is the set of all points x y in the plane that satisfies the equation y f x.
In the common case where x and f are real numbers these pairs are cartesian coordinates of points in two dimensional space and thus form a subset of this plane.
Select all of the following graphs which represent y as a function of a 3 2 1 3 a 3 3 2 34 3 2 3 4 ta 5 32 tt get more help from chegg solve it with our calculus problem solver and calculator. We can have better understanding on vertical line test for functions through the following examples. If any vertical line intersects the graph more than once then the graph does not represent a function. A graph represents a function only if every vertical line intersects the graph in at most one point.
