Which of the following are possible equations of a parabola that has no real solutions and opens downward?
y > = -(x + 4)2 - 2
y > = -(x + 4)2 + 2
y > = -x2 - 2
y > = (x - 4)2 + 2
y > = -(x - 4)2 - 2

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

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.

step-by-step explanation:

b and c

x = 3 ± √(5+y)
