WebSep 7, 2024 · Definition: Derivative Function. Let f be a function. The derivative function, denoted by f ′, is the function whose domain consists of those values of x such that the following limit exists: f ′ (x) = lim h → 0f(x + h) − f(x) h. A function f(x) is said to be differentiable at a if f ′ (a) exists. WebCalculus Derivative Calculator Step 1: Enter the function you want to find the derivative of in the editor. The Derivative Calculator supports solving first, second...., fourth derivatives, as well as implicit differentiation and finding the zeros/roots. You can also get a better visual and understanding of the function by using our graphing tool.

WebJul 7, 2015 · 1 Answer Sorted by: 1 You lost a constant at T V C ( Q) = ∫ M C ( Q) d Q because for any α ∈ R the derivative of T V C ( Q) + α will be M C ( Q). The way to get this constant: If there is no quasi-fixed cost then T V C ( 0) = 0. From this and by calculating T V C ( Q) for Q ≤ 50 you will get the value for T V C ( 50). (Seems to be 3750.) WebTo find where the average cost is smallest, first calculate c' (x), the derivative of the average cost function. Then use a graphing calculator to find where the derivative is 0. Check your work by finding the minimum from the graph of the function (x). C (x) = 1/2x^3+4x^2-4x+35 Determine the average cost WebFeb 21, 2024 · 1.
