Question

check my work?

Answer 1

Reya and Ian are both concerned about class size. Reya stated that she would like to attend a small school with fewer than 1,000 students in her freshman class, while Ian stated that he would like to attend a larger school. Look at the table below:
School
Freshman Class Two Years Ago
Last Year’s Freshman Class
Current Freshman Class
Gore College
630
675
720
Douglas University
630
690
750
Hughes University
600
680
760
A. Using g(x), d(x) and h(x), write a function to represent the class size data for each school.

Answer 2

Gore: g(x) = 45x + 630

Answer 3

Douglas: d(x)= 60x + 630

Answer 4

Hughes: h(x) = 80x + 600

Answer 5

Yes?

Answer 6

yes

Answer 7

correct.

Answer 8

IM A GENIUS! so in 4 5 and 6 years from now it'd be this?
years Gore Douglas Hughes
4 810 870 920
5 855 930 1000
6 900 990 1080

Answer 9

I checked a few of them and there are correct. As long as you did the arithmetic correctly you got them all...

Answer 10

If Reya and Ian graduate on time, which value will represent their freshman year in college?

Answer 11

You could have tweaked your equations so that x is the years from when both started school. (you have x representing the time from 2 years earlier)

Answer 12

I can't.

Answer 13

For example,
Gore: g(x) = 45x + 630
when x is 0, you get 630... which according to the table, is Freshman Class Two Years Ago

if you wanted x to represent "now", you would use the same slope,
Current Freshman Class 720
but the point (0, 720)
in other words, g(x)= 45x + 720

It does not matter too much, but if you use your first equation
g(x) = 45x + 630
x= 2 is now, and x=6 is 4 years from now, when they graduate.

if you use the other equation g(x)= 45x + 720
then x=4 is 4 years from now

Answer 14

clear as mud ?

Answer 15

hahah yes, so for 2 years behind i can say if they graduate on time its f(6)?

Answer 16

after reading it over, I am thinking that their freshman class (using your version) starts at x= 3 ... in other words, the Current Freshman class is one year before they start.

Answer 17

The writing is not clear, but I think they are saying
"If Reya and Ian graduate on time FROM HIGH SCHOOL, which value will represent their freshman year in college?"

(and they don't say what grade they are in right now... we have to assume they are seniors in high school)
