A function is initially defined by the set of coordinate pairs ((_3,7), (1,5), (4,13)). Which coordinate pair below, if added to this set, prevents the set from representing a function?

(1,4)

Step-by-step explanation:

Given

Required

Which pair makes the relation not a function?

A function is defined as:

Where each x values (domain) are unique and different from one another.

In the given function, the x values (domain) are: -3, 1 and 4

To get a pair that makes the relation, not a function; we have to select from the given options, any option that has either of -3, 1 and 4 as its x values.

From the list of given options.

4) (1,4) has an x value of 1

Hence, the solution to this question is (1,4)

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
