A function is a relation in which every input has one output.

Relation 1 is a set of points where each x value has a single y value. function

Relation 2 is an equation of a line. With the exception of vertical lines, all lines are functions. This example is not a vertical line. function

Relation 3 is a graph of an absolute value equation (y=|x|-1). We can use the vertical line test and see that it is a function.

Relation 4 has input two traveling to two outputs (A and B). So it is not a function.

Answer:

b. CHISQ.TEST

Step-by-step explanation:

Notation and previous concepts

A chi-square test is "used to test if the variance of a population is equal to a specified value. This test can be either a two-sided test or a one-sided test. The two-sided version tests against the alternative that the true variance is either less than or greater than the specified value"

The statistic is given by:

$\chi^2 = \sum_{i=1}^n \frac{(O_i-E_i)^2}{E_i}$

In order to calculate the p value we need to have in count the degrees of freedom , on this case $df=(rows-1)(#cols-1)$ . And we can calculate the p value would be given by:
