How do I read the equation (function) y=0.03x^2+0.14x+1.43?
Do I have to complete the square to find the vertex, max., min., etc.? This function is part of a word problem that I am trying to do. I would appreciate any help.

Well, you could multiply everything by 100 to get an easier function:
y=3x^2+14x+143
in which you could try and use the quadratic theorem
[b +/ sqrt(b^24ac)]/2a
Giving you:
14 +/ sqrt(196(1716)/60
[14 +/ sqrt(1912) ]/6
You cant simplify too much. But you get the idea from here. Is this the answer you were looking for?
