This is rather a sneaky question. You don't know exactly what numbers you can use and what numbers not.
For example, are you allowed to use x = - 3. The answer is yes
f(-3) = 2*7^(-3) = 2/7^3 = 2/147.
How about 0? If there is going to be a problem, zero is usually the number that causes the problem.
f(0) = 2*7^(0) = 2 * 1 = 2 and in this case 0 is just fine.
How about positive numbers? No they are all good.
So the range is -∞ < y < ∞
Answer:
C. <em>$720.37</em>
Step-by-step explanation:
An investment of $2,000 is earning interest at the rate of 6.2% compounded quarterly over 5 years.
We know that,
here,
A = Future amount,
P = Principal = $2000
r = Rate of interest = 6.2% = 0.062
n = Number of period = 4 (as compounded quarterly)
t = time period = 5 years
Putting the values,
So the interest will be,
