Answer:C
Step-by-step explanation:
The amount of money a customer will earn between 3rd year and fifth year will be given as follows:
FV=p(1+r/100)^n
where:
FV=future value
r=rate
n=time
The amount earned in the first 3 years will be:
FV=2000(1+5.2/100)^3=$2,328.50
The amount earned in 5 years will be:
FV=2000(1+5.2/100)^5=$2,576.97
The amount earned between 3rd and 5th
=2,576.96-2,328.50
=$248.46
The derivative of f(x) at x=3 is 2x=6 approaching from the left side (apply power rule to y=x^2). The derivative of f(x) at x=3 is m approaching from the right side. In order for the function to be differentiable, the limit of derivative at x=3 must be the same approaching from both sides, so m=6. Then, x^2=mx+b at x=3, plug in m=6, 9=18+b, so b=-9.
