The given quadratic functions are:



We want to order these functions, from the widest to the narrowest.
How wide the graph will open depends on the absolute value of the coefficient of the function.
The smaller the absolute value of the coefficient, the wider the graph.
Since

Therefore from the widest graph to the narrowest graph, we have:

Answer:
Im not quite sure the awenser to part 1 but part 2 is yes they are
Answer:
vol of cylinder = per. of base x height + 2 (area of base)
area of base = pi x r^2
4pi = pi r^2
4=r^2
r=2
per of base = 2 x pi x r
2xpix2=4pi (same as area cause 2x2 and 2^2 is the same thing)
4pi + 2(4pi)
4pi + 8pi
<u>12pi = volume</u>
