The average rate of change of a function f(x) over some interval [a, b] is the difference quotient,
which corresponds to the slope of the line connecting the points (a, f(a)) and (b, f(b)) in the graph of f(x).
Given f(x) = 3x² - x³ (correct me if I'm wrong, the exponents look cut off in your screenshot), the average rate of change on [1, 5] is
Answer:
A: might be x < 4.5
B: might be the same as a
c: x > 4.5

1st question: M=22.62 while C=75.38
2nd question: M=.22 while C=1.97
If a mirror costing x dollars is marked up 30%, then we have to find x such that 30%x+x is 98 dollars.
We are solving:
.3x+x=98
Combine like terms:
1.3x=98
Divide both sides by 1.3:
x=75.38
M=98-75.38=22.62
C=75.38
So M=22.62 while C=75.38.
If ream of paper cost x and is marked up 11%, then we have to find x such that 11%x+x is 2.19.
.11x+x=2.19
1.11x=2.19
x=1 97
M=2.19-1.97=.22
So M=.22 while C=1.97
