You must do in this case is composition of both functions:
 a (x) = 3x + 1
 b (x) = root (x-4)
 Making the composition
 b (a (x)) = root ((3x + 1) -4)
 Rewriting:
 b (a (x)) = root (3x-3)
 b (a (x)) = root (3 (x-1))
 Answer:
 The domain of the function is:
 x> = 1

60.April would like to invest $200 in the bank for one year. Three banks all have a nominal APR of 1.5%, but compound the intere
mojhsa [17]

Answer:

$203.02

Step-by-step explanation:

Since the bank in question compounds interest continuously, the following equation should be used to determine the final balance (B) in April's account:

B= 200*e^{i*t}

Where "e" is a mathematical constant approximated as 2.7183, "i" is the interest rate (1.5%) and "t" is the investment time in years (1):

B= 200*e^{0.015*1}

B= 203.02

April's balance would be $203.02 after one year.
