I am assuming this is a triangle.....P = a + b + c
P = 2a - 3 + 2a + 3a + 1....combine like terms
P = 7a - 2 <==
Note: The function is below the graph, so it is less than.
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:
1) 18
2) Tuesday, Thursday, Saturday
3) Weeks 2 and 4
