Question

A graph with a curvy line across quadrant | and || does this line show a function

Answer 1

Yes, a curvy line that passes through the quadrants | and || could show a function. A function is any relation between a set of inputs and a set of outputs where each input is related to exactly one output. In this case, the curvy line represents how one set of values (inputs) corresponds to another set of values (outputs) as shown by the line. Thus, it could represent a function if each input value on the line corresponds to exactly one output value.
