Function And Not A Function Examples

Solution This is a function as each input has a unique output. No output is paired or mapped with two or more inputs. This is not a function as the output value quot5quot is paired with input values quot-5quot and quot10quot, respectively, which violates the conditions of a function.

Examples of not functions 1. A circle if we take x as the input and expect the output to be y, the circle has two possible outputs for each x-coordinate. Therefore, it does not satisfy the definition of a function. 2. A vertical line if we have a vertical line, it can pass through multiple y-coordinates for a single x-coordinate, violating

A function in mathematics is a specific relationship where each input corresponds to exactly one output. This unique pairing ensures clarity and predictability in mathematical operations. However, not all relationships qualify as functions. Here are some examples of relationships that do not meet the criteria for functions

Since the input value 1 has two different outputs 2 and 4, this R is not a function.. For a visual check, one can use the vertical line test on a coordinate plane.If any vertical line intersects the graph of the relation at more than one point, the relation is not a function.Here's an example of a graph on a coordinate plane that demonstrates a function vs. not a function

For example, in the following mapping diagram, y is a function of x, but x is not a function of y. Vertical line test for graphs To determine if y is a function of x given a graph of the relation, we can use the following criteria if all vertical lines that can be drawn pass through a single point on the graph, then the relation is a function.

For example, the term quotoddquot corresponds to three values from the range, 92921, 3, 592,92 and the term quotevenquot corresponds to two values from the range, 92922, 49292. This violates the definition of a function, so this relation is not a function. Figure 9292PageIndex192 compares relations that are functions and not functions.
