Give an example of a differentiable function ƒ whose first derivative is zero at some point c even though ƒ has neither a local maximum nor a local minimum at c.

Is it true that every function y = ƒ(x) that is differentiable on [a, b] is itself the derivative of some function on [a, b] ? Give reasons for your answer.

Let f be a function on [0, 7] whose second order derivative is continuous and f(T) = 1. Suppose that | (f(2) + f"(x)) sin a da = 4. Compute f(0).

Consider the following function which is defined for all x and y: f(x, y) = 2(1-p²)x²y² - x² - y² + 3pxy + 2x+4y+2 where p is a constant. (a) Find the first order derivatives of f and enter them as functions of x, y and p (b) Find the second order derivatives of f and enter them as functions of x, y and p (c) For p = 1, find the stationary point (x*, y*).

Let f and g be functions satisfying that f(1) = 3, g(1) = 4, ƒ'(1) = 1, g' (1) = 5. For the following function h(x), find h' (1). Answer: h(x) = 2ƒ(x) + 3g(x).

It costs Sugarco 25¢/lb to purchase the first 100 lb ofsugar, 20¢/lb to purchase the next 100 lb, and 15¢ to buyeach additional pound. Let f(x) be the cost of purchasing xpounds of sugar. Is f(x) continuous at all points? Are thereany points where f(x) has no derivative?

Consider a dataset of numbers y1, y2, ..., yn and  the linear function f(x) = 9x − 4.  Prove or find a counterexample to disprove. If a ≤ b, show that f(a) ≤ f(b). since it is a monotonic function that is increasing i was thinking of doing the derivative to prove it but i dont what else to do more to prove it after doing it.
