Question 1 (1 point) Saved KUSSLIUII J 1 1 HWILL Question 2 (1 point) re -2 is equal to Consider the function Suppose @ = c: (t ) and y = y(t) satisfy by + ell = : - 1. and f (*) = - VI'+1 *(0) = 20(0) = 0, and Oe 20 I'(0) = 5. Then y' (0) is equal to The function is increasing in -Do, 0) and decreasing in none of the other four. " none of the other four. (0, 0). O0. Onone of the other four. 0-8e -20 04/5. The function is increasing in (-00, 00 )- O1 The function is decreasing in 01/5. (-Do, 00). The function is decreasing in (-DO, U) and increasing in (0. 00). Question 4 (1 point) Question 5 (1 point) Suppose the demand function is Suppose the cost function is x = f(p) = V100 - 2p. At C(a) = x In(a + 1). The p = 20, the demand is marginal cost at @ = 1 is equal to Onone of the other three. none of the other four. unitary. O inelastic. O In 2. Oelastic. O1. Oh + In 2
