Step-by-step explanation:
b)
Answer: Second Option

Step-by-step explanation:
The exponential growth functions have the following form:

Where a is the main coefficient, b is the base and x is the exponent.
For this type of functions the base b must always be greater than 1. Otherwise it would be an exponential decay function
Among the options given, the only function whose base is greater than 1 is the second option:

Answer:
244
Step-by-step explanation:
74+42=116
360-116=244.
Answer:
$30
Step-by-step explanation:
T = 750
B = 60(12)
T - B = X
750 - 720 = 30
