The equation of a parabola is y=a(x-p)^2+q, where (p,q) are the coordinates of the vertex. The value of p will be your axis of symmetry.
(x+2)^2=0
In order for 0=0
x=-2
So your axis of symmetry is x=-2
Each half-life reduces a sample by one half.
So after 1 half-life there is 1/2 left
2 half-lives 1/4
3 half-lives 1/8
4 half-lives 1/16
5 half-lives 1/32
There would be (1/32) of 120 remaining.
or 3.75 grams.
