Question

1. (5 points) If x = c is a critical point of the function f(x), then f(c) must be a maximum or minimum. True False 2. (5 points) The rate of change of a function is always the largest at a point of inflection. True False 3. (5 points) If the elasticity of demand, E, is greater than 1, then demand is said to be elastic. True False 4. (5 points) The derivative of H(t) = 4t ln(t) is given by H'(t) = 4/t. True False 5. (5 points) If a function is concave up, then that function must be increasing on its domain. True False 6. (5 points) Given the function v(s), we have that v'(7) = 0 and v''(7) = 200. This information means that at s = 7, the function v(s) has a minimum. True False 7. (5 points) Given the function v(s), we have that v'(7) = 0 and v''(7) = 200. This information means that at s = 7, the function v(s) has a minimum. True False
