Answer:
A- When they are inverse functions
C- when they are equal for all values of x
Step-by-step explanation:
The order of function application in a composition can be reversed if ...
- the functions are inverses of each other
- the functions are identical (equal for all values of x)
_____
In the first case, the composition gives an output equal to its input for the functions in either order.
In the second case, you cannot tell the functions apart, since they produce the same output for the same input. Hence, you can't tell if they are reordered or not.
Hi,
I think this is the table, correct?
Number of Tubes 3 5 7
Cost ($) 12 20 28
we can calculate the prize as the number of tubes multiplied by 4:
3*4=12
5*4=20
7*4=28
which means that one tube costs 4 dollars!
However, in the store A two tubes cost 7, which means that one costs half of this -3.5
So Store B is more expensive (4 dollars per 4 rather than 3.5 as in Store A).
The taxi ride is an illustration of a linear proportional equation
The taxi ride was 13.25 miles
<h3>How to determine the number of miles</h3>
From the question, we have:
- Total cost = $39.75
- Cost per mile = $3.00
The number of miles (n) is the quotient of the total cost of the ride, and the cost per mile.
So, we have:
n = 39.75/3.00
Evaluate the quotient
n = 13.25
Hence, the ride was 13.25 miles
