When x= 120
y =18868. ( That is the minimum point in this quadratic, aka vertex.)
I can't seem to figure this quadratic -
An aircraft factory manufactures airplane engines. The unit cost C (the cost in dollars to make each airplane engine) depends on the number of engines made. If x
engines are made, then the unit cost is given by the function
C(x) = 0.2x^2 - 48x + 21,748
What is the minimum unit cost?
Do not round your answer.
