Question

The attendances at the high school basketball games seems to be affected by the success of the team. The graph below models the attendance over the first half of the season. Which function would also represent the data shown in the graph below where a represents the attendance and g represents the number of games the team has won?

a = 2(3)^g
a = 25g + 100
a = 25g² + 100
a = –25g² + 100

Answer 1

Would the answer be 25g^2 + 100?

Answer 2

try to fill in the data you have in each of the equations and see which one fits.

for example, one dot is g=2, a=150

let's try to first solution:

a= 2(3)^g
a = 2.3²
a = 18
so this one is wrong

a= 25g + 100
a= 25. 2 +100
a= 150
this seems to be working for this point

a= 25g² + 100
a= 25. 2² +100
a= 200
this one doesn't seem to fit either

a= -25g² +100
a= -25 .2² +100
a= -100 +100
a= 0
so this isn't right either.
