%path = "maths/linear system/quadratic cost function" %kind = chindnum["problems"] %level = 10 The overall costs of a business are modeled with a quadratic function
\[K(x)=ax^2+bx+c\] The overheads (fixed costs) are known to be €{{chiven.cf}}. With {{chiven.A[0][1]}} units the costs are €{{chiven.b[0]+chiven.cf}} and with {{chiven.A[1][1]}} units they are €{{chiven.b[1]+chiven.cf}}. Determine the coefficients a, b, c of the cost function and enter them rounded to integers %chq(chames=['a = ','b = ','c = '])
