The number of people attending graduate school at a university may be
modeled by the quadratic regression equation y = 6x2 - 30% +6, where x
represents the year. based on the regression equation, which year is the best
prediction for when 906 people will attend graduate school?

a. year 11
b. year 15
c. year 6
d. year 9

  B.  Year 15

Step-by-step explanation:

Along with helping you do quadratic regression, a graphing calculator can help you evaluate quadratic functions. This one has a value of 906 when x=15.

__

By hand, you would set y=906 and solve for x:

  906 = 6x^2 -30x +6

  151 = x^2 -5x +1

  156.25 = x^2 -5x +6.25 . . . . . . add 5.25 to complete the square

  12.5^2 = (x -2.5)^2 . . . . . . . . . . write as squares if you like

  12.5 = x -2.5 . . . . . . take the positive square root

  15 = x . . . . . add 2.5

Year 15 is the year 906 people are predicted to attend graduate school.

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to

pls mark as brainliest

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
