I’m pretty sure it would be a, because the first set is going up by five and the second is going up by four.

Finding the extreme point :

Now,
f''( x ) at x = 1/3 and -1 is :

Therefore, it is maximum at x = -1 and minimum at x = 1/3 .
Hence, this is the required solution.
Answer:
The account interest rate is 0.80%
Step-by-step explanation:
A=P(1+r/100)^10
1462=1350(1+r/100)^10{divide both sides by 1350}
1462/1350=(1+r/100)^10{find the 10th root of both sides}
1.00800=1+r/100{multiply through by 100}
100.800=100+r
r=100.800-100
r=0.80%
