The mapping diagram shows a function. What could be a possible value for the missing number n? A. 7
B. 9
C. 8
D. 15

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.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
