Which of the relations given by the following sets of ordered pairs is a function?
select one:
a. {
(212)
(212)
}
b. {
(−5,−−4,−−3,−−4,−−2,−1)
(−5,−−4,−−3,−−4,−−2,−1)
}
c. {
(0,−6,−3,,−,11)
(0,−6,−3,,−,11)
}
d. {
(8,−4,,,−1,2)
(8,−4,,,−1,2)
}

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
