She has two thirds of the marbles left after giving one third of them to John. The amount of marbles she has left is found from:
$\frac{2}{3}(12a+21)=8a+14$
The answer is: 8a + 14 marbles.

Mathematics

1. domain(-6,-1,1,5,7);range (-4,-1,2,4)/domain (1,-3,-2); range (-2,5,1)/domain(1,2,3,4,5,6);range(-1,0,1,2,3,6)

2. 1st and 4th are a function because if you draw a line vertically across it will only intersect it once.
