For a distance vs time graph. X axis is time and Y axis is distance. at t=6s, dist=5m at t=8s, dist=6m at t=10s, dist=7m at t=12s, dist=8m I don't see any of those as choices.

Problem 1 A is not the answer. f(4)- f(1) =11 - (-1) = +12 -------------- Problem 3. C looks correct

Problem 2. The answer is not B, (x=0).

Problem 1. The answer is NOT D. The average rate of change is: for x=1, f(1)=-3 for x=4, f(4)=-3 Average rate of change is 0, not a negative number. One of the answers does give a negative average rate of change.

Let B = the "break even" number of books. Production costs=$76,322 + B * $10 Total Sales = B * $25.50 Setting these equal... Total sales = Production costs or... $76,322 + B * $10 = B * $25.50 Solve for B

number 4 should be +5 6 is wrong.
