The cost of manufacturing a particular videotape (in dollars) is 4:00: 10,003+ 10:, where x is the number of tapes produced. The average cost per tape (in dollars), denoted by E(x), is found by dividing C(x) by x. Find 11m E(x). x-oo (0 does not exist 0 $8 0 $5 0 $10 D Question 5 1 pts Find the average rate of change for the function over the given interval. y= 3 x - 2 between x = 4 and x = 7 O 2 07 O O 10Question 7 Find the point from those given that has the given property.
