The graph of f(x) = 2x + 9x. - 108x + 14 has two horizontal tangents. One occurs at a negative value of x and the other at a positive value of x. What is the negative value of a where a horizontal tangent occurs? What is the positive value of where a horizontal tangent occurs? If f(x) - f'(x) = 3 - x 7+ x ", find: = Suppose a product's revenue function is given by R(q) = dollars and q is units sold. Find a numeric value for the marginal revenue at 27 units, and record your result in the box below. Answer: MR(27) $ per unit - 6q + 1000g, where R(q) is in = 7 6 x If f(x) = 3 + + X Find f'(1). find f'(x). Use the chain rule to find the derivative of f(x) = 3(- 4x You do not need to expand out your answer. f'(x) = 17 +4x8) 7 Find (5 ln(x)) dx 9 2 = (+) x 1 Let f(x) = f'(x) = 10 (1) If f(x) = x0, then f'(x) = = (2) If g(x) = 6x5, then g'(x): 1 (3) If h(x) = -1/ then h'(x) x5 = =
