State which of the following ordered pairs is a function. set a: (-1, 0), (-2, 1), (4, 3), (3, 4)set b: (1, 4), (2, 3), (3, 2), (4, 1)set c: (2, 1), (3, 2), (2, 3), (1, 4)a. set ab. set bc. both set a and set bd. set c

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.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.
