Which statement is not true? f. a set of ordered pairs that describes a function cannot have any y-value repeated. g. a table of values describes a function if all the x-values are different. h. a mapping is a function if each x-value is paired with exactly one y-value. j. a graph describes a function if no point on the graph lies directly above or below another of the graph.

The answer is F. A set of ordered pairs that describes a function cannot have any y-value repeated.

Why??

F - it can be a function even if a y - value repeats itself its the x - values that cannot repeat in order to be a function.

G - this is true as stated above.

H - a mapping is a function if each x - value is paired with only one y - value. If an x - value was paired with multiple y - values then its the same thing as repeated x - values.

J - this is true. To check if a graph is a function try the vertical line test. Simply take a ruler holding it vertically ( up and down ) and place it over a point on the graph. If there is another point lined up with the first one ( above or below ), then it is NOT a function.
