Answer: A. The expression
reveals the approximate rate of increase in the number of subscribers if measured six times a year.
Step-by-step explanation:
Here, The number of subscribers to an online magazine is increasing by 34% each year. The function represents the number of subscribers after t years.

where
represents rate of increase in the number of subscriber.
If rate is measured six times a year
then the number of subscriber, 
( approx)
Thus, when we measure increment in six times a year then the rate rate of increase in the number of subscribers=
Therefore Option A is correct.
Note: Option B) is incorrect because rate of increase in the number of subscribers if measured three times a year =
( approx)
Option C) is incorrect because rate of increase in the number of subscribers if measured four times a year =
( approx)
Option D) is incorrect because rate of increase in the number of subscribers if measured two times a year =
( approx)
You first gave to identify what values belong to a, b, and c then plug them into the quadratic formula then solve
X/2 = 8
▶ ️2 = 8 × X. (transposing X to RHS )
▶️ 2 = 8X
▶ ️X = 8/2. (transposing 2 to RHS )
▶️ X = 4
hence the value of X is 4.
