6- Given the demand function P= 2,000 - 4Q. Find the Total Revenue (TR) and the Marginal Revenue (MR) functions. * TR= 2,000Q - 4Q2, MR = 2,000 - 80 O TR= 2,000 - 4Q", MR = - 8Q O TR= 2,000/Q - 4, MR = -2,000/02 - 4 TR= 2,000Q - 402, MR = 2,000 0 TR= 2,000 - 80 , MR = - 8 7- Based on the previous question, calculate the Total Revenue (TR) and the Marginal Revenue (MR) for Q = 10.* OTR = 1,920, MR = -8 1 TR = 196 MR = -24 TR = 19,600, MR = 2,000 TR = 19,600 MR = 1.920 TR = 1,600, MR = -80
