graph becomes slimmer, so definitely be multipled 1/2
Parent function: y = f(x) = x^2
given function: y = g(x) = 3 (x+1)^2
=> g(x) = 3 * f(x + 1)^2
So, from the point of view of graphs, the given function, g(x), is the parent function, f(x) = x^2, shifted one unit to the left and amplified by a factor of 3.
It should be less then 2000 even though 11000-9000=2000 there are the ends, the thousands place should not be the only thing you should worry about
