Tutor description

Find an equation of the tangent to the curve y(x) = x^2 - 3x + 2 at the point (1, 2). If s = 2t^2 + 5t - 8 represents the position of an object at time t, find the acceleration (s") of this object at t = 2 sec. Find the absolute extreme values of the function f(x) = 3x - 4 if -2 ≤ x ≤ 3 Determine all critical points for the function Q(x) = x^3 - 12x + 5 Calculate where the minimum value of the cost function C(x) = x^2 - 20x + 300 occurs and what that minimum value is. A TV retailer supposes that in order to sell n number of TVs, the price per unit must follow the model p = 600 - 0.3n. The retailer also supposes that the total cost of keeping n number of TVs in inventory is given by the model C(n) = 0.3n^2 + 5,000. How many TVs must the retailer keep in inventory and sell in order to maximize his profit? And The rest.
