2 answers:
Answer:
Option D - by adding 3, then 9, then 15, …
Step-by-step explanation:
Given : Function
To find : How do the y-values of this function grow?
Solution :
From the following options the most suitable option is D.
As if we are going to add term and terms our y-values increases.
When we add any term in the function the y value value increases.
If we adding 3, then 9, then 15, … the function continuously grow term by term.
The new function became
Therefore, Option D is correct.

Answer:
Consider the complete question is,
'Ms. Lane borrowed $1,000 from her bank for one year at an interest rate of 10 percent. During that year, the price level went up by 15 percent. Which of the following statements is correct?
a. Ms. Lane will repay the bank fewer dollars than she initially borrowed.
b. Ms. Lane's repayment will give the bank less purchasing power than it originally loaned her.
c. Ms. Lane's repayment will give the bank greater purchasing power than it originally loaned her.
d. Ms. Lane's repayment will give the bank the same purchasing power that it originally loaned her.'
Solution :
We have,
The borrowed amount, P = $ 1,000,
Interest rate, r = 10% = 0.1,
Time, t = 1 year,
Thus, the returned amount,
∵ A > P
⇒ Ms. Lane will repay the bank greater dollars than she initially borrowed.
Now, the price level went up by 15 percent,
∵ 1000 + 15% of 1000 = 1000 + 150 = 1500
And, 1500 > 1100
⇒ Ms. Lane's repayment will give the bank less purchasing power than it originally loaned her.
