which quadratic function would that be?
this seems like you'll want to use calculus. finding the max/min values using the first derivative test. do you know derivatives/calculus?
Not the answer you are looking for? Search for more explanations.
i know a little.
C' = 2 * 0.45x - 110 = 0
by taking the first derivative and setting it equal to 0 you can get the critical points
0.9x - 110 = 0
.9x = 110
these are points where the function is at a max or minimum. since it is a parabola there should be only one, and hopefully it is a min (a second derivative test could confirm this).
x = 122.22
And basically whatever heisenberg said. Please fan us both if we helped. Thanks! =)
bahrom is exactly right, but what you get from this is the x coordinate of the critical point (min or max value). since the question wants the actual value of the function, plug this x value in the original equation: C(122.22)
yup, good lol I missed the ending.. i just got back from college.. brains not functionin properly lol
what happened to 10000?? you just kick that off??
when you take the derivative of a constant it is 0.
