Question

Is the relation given by the set of ordered pairs below a function? (Yes or No)

Answer 1

Answer:

No

Step-by-step explanation:

The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular X value. The Y value of a point where a vertical line intersects a graph represents an output for that input X value. If we can draw any vertical line (left to right) that intersects a graph more than once, then the graph does not define a function because that X value has more than one output. A function has only one output (X) value for each input value.

EXAMPLES:

(3,-7), (2,4), (-3,-7), (3,0), (0,2)  

The first numberin each set is th X value or output.

The 3 has two Y values, -7 and 0, it can only have one Y value.

Only one X can have a one Y vale to make it a function.
