F (x) = x^2

g (x) = - 5x^2 + 100 x - 450 = - 5 (x^2 - 20x + 90) = - 5 (x^2 - 20x + 100 - 10) =

-5 (x^2 - 20x + 100) + 50 = - 5 (x - 10) ^2 + 50

The negative sign in front of x^2 means that the graph f (x) = x^2 is reflected over the x-axis.

The constant term + 50 means that the reflected graph is shifted up 50 units.

The 10 subtracting from x inside the parenthesis means that the graph is shifted 10 units to right.

The 5 multiplying the term x^2 means that the graph is stretched upward, but this is not mentioned.
