What is the median of the data set represented,

10 , 10 , 12 , 13 , 14 , 15 , 18 , 19 , 19.

14

Step-by-step explanation:

The median is 14, because it is the exact middle of the data set. I hope this helps :)

step-by-step explanation:

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.
