For each of the total cost functions, write the expressions for the total fixed cost, average variable

Question:

For each of the total cost functions, write the expressions for the total fixed cost, average variable cost, and marginal cost (if not given), and draw the average total cost and marginal cost curves.
a) TC(Q) = 10Q
b) TC(Q) = 160 + 10Q
c) TC(Q) = 10Q2, where MC(Q) = 20Q
d) TC(Q) = 10√Q, where MC(Q) = 5/√Q
e) TC(Q) = 160 + 10Q2, where MC(Q) = 20Q
