do you have the question? if you post the question someone will be happy to help you

Answer 2

@zepdrix

Answer 3

part a
think about y = mx + b
y = function m = slope and b = intercept
doing students each year 2ys ago then last year then this year
change per year = 45
school 1 g(x)= 45x + 630

do the same for the other 2 schools

Answer 4

part b
find when x = 4, when x = 5 and when x = 6 for each function

Answer 5

^^^ Be careful with part b). If you choose x = 0 to represent 2 years ago, then for part b, x should be 6, 7 and 8.

But I'd prefer to choose x = 0 to represent the current year, x = -1 last year, x = -2 two years ago. Then g(x) = 45x + 720. If this equation is used, then for part b, x will be 4, 5 and 6.

Answer 6

so far i have
d(x)= 60x+630
h(x)=80x+600 for part a
is this correct?

Answer 7

yes part a

Answer 8

@aum can you please finish this part c and d thanks.

Answer 9

@Hero @ jim_thompson @zepdrix please help

Answer 10

a) Let x represent the CURRENT year.
g(x) = 45x + 720
d(x) = 60x + 750
h(x) = 80x + 760

b) In 4 years,
g(4) = 45*4 + 720 = 900,
d(4) = 60*4 + 750 = 990
h(4) = 80*4 + 760 = 1080

Complete the data when x = 5 and x = 6

c) Assuming Reya and Ian graduated this year and that they are attending a four year college: set x = -4 and calculate g(-4), d(-4), h(-4).
Create a new column on the right to the given table, label the column, "Your Freshman Year", and enter below it g(-4), d(-4), h(-4).

d) Look at the last column at the number of students that were in the Freshman class four years ago. Which one would your prefer based purely on the number of students that were in that class that year. State your reason. Smaller class size may mean more access to teacher? More students means better chances of finding compatible friends?
