We are given function: y= 
Where, x is the number of hours after 5a.m.
We need to approximates the number of people standing in line to catch a commuter train at 7 a.m.
From 5 a.m. to 7 a.m. total number of hours = 7-5 = 2 hours.
So, we need to plug x=2 in the given function.
Plugging x=2 in
, we get

Let us simplify it now.
2^2= 4.
Therefore,

= -20.524 + 63.642 - 3.333.
= 39.785 or 40 approximately.
Therefore, the number of people in line at 7 a.m. is approximately 40 people.
Option D.40 is correct option.
First if there are 47/80 we have to estimate like 47 is 50 and 82 is 80
You have to simplify like this
(-5)(-8)=40
Well how far away is t (-3) from r (12)?
It's 15 away. It gets 15 less, so q will be 15 more.
12+15=27
q is 27
