What value of k will make this relationship NOT a function? {(-7, 2), (-1,0), (4,8), (k, 0)}
A) 2
B) -7
C) 8

the correct answer is b.

Step-by-step explanation:

it is b because if you plug in -7, two of the x-values will have -7 making the x-values the same and in order to be a function all x-values have to be different.

step-by-step explanation:

cats

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
