Looking at the following plot of a firm's production function, represented by isoquants for production levels and isocost lines for different total costs of production. Which of the following are true? Question 11 Select all that apply: a. Points a and c are each cost minimizing points for the firm at different levels of output. cross out b. Point d will have higher output and higher total cost than point c cross out c. Point e has more output than point d, and a higher total cost. cross out d. The production function exhibits increasing returns to scale. cross out e. It's clear that Point c does not correspond to a cost-minimizing bundle of inputs
