Answer:
y=-0.215x^2+35
Step by Step:
Let,
,
,
, 
We know that, the general equation of the parabola.


Substitute the value of
in equation
and find the value of 







Hence, the equation of the parabola is:

We can withdraw a equation to give mexico population
P = M.(1 + i)^t
So,
First of all, how many years passed? 2015 - 2000 = 15. Our time is 15, our annual rate is 1,7%, time to calc.
P = 100350000.(1 + 1,7%)^15
1,7% = 0,017
P = 100350000.(1 + 0,017)^15
P = 100350000.(1,017)^15
P = 100350000.1,2876988084901218382866596204289
P = 129220575,43198372647206629291004
Rounding
P = 129,220,575
Hi there! The answer is B. it would be less steep.
The change of the function (in this case) influences the slope of the line. Since we've modified the slope from 5 to 3/4, the line will be less steep.
