<span>Since there were 2100 people on saturday and 4900, lets do the math..
#1) Line up the numbers, when it comes to adding it doesn't really matter which goes on the top.
#2) Add or use a calculator for help.
#2b 4900-2100=2800
Thats all!
Hope this help!

f(x) is a quadratic equation with the x-side squared and a is positive which means that the graph of the function is a parabola facing up. The range of f(x) is given by {y|y ≥ k}, where k is the y-coordinate of the vertex.
, written in vertex form is
, where (h, k) = (-1, -11)
Therefore, range ={y|y ≥ -11}
