why can you specify a point on the graph of a function by on

why can you specify a point on the graph of a function by only giving its x-coordinate? can you do the same with the y-coordinate? why or why not?

Solution

no we cannot  specify a point on the graph of a function by only giving its x-coordinate

no we cannot  specify a point on the graph of a function by only giving its y-coordinate

because in a cartesian plane these are 2 coordinates for each point indicating x and y which is unique,

i.e, every point has its own pair of x and y coordinate which is written as ordered pair (a,b).

on x axis y coordinate is zero, on y axis x coordinate is zero
