Answer:
Step-by-step explanation:
A comparison between a function and its inverse would show that the domain and range of the original function swap. The domain of the function becomes the range of the inverse, the range of the function becomes the domain of its inverse.
Looking at ordered pairs of the function and its inverse would look like this:
(2,4) on the original function becomes (4,2) on the inverse.
While the graph of a function and its inverse are noticeably different an important thing to note is that it is merely a reflection across the line y=x.
So even though they appear different you are looking at the same relationship just as y vs. x instead of x vs. y
I hope this helped you because i barley understood this myself.

something is wrong on your question
ie 6x^ is there a missing number
Answer:
Ashley read 27 books and her brother read 6 books.
Step-by-step explanation:
Let the number of books her brother read be x.
No. of books her brother reads = x
No. of books Ashley reads = 4x + 3
No. of books her brother reads + No. of books Ashley reads = 33
x + 4x + 3 = 33
Evaluate.
5x + 3 = 33
Isolate 5x.
5x = 33-3
= 30
Find x.
x = 30 ÷ 5
x = 6
Amount of books her brother reads = 6
Amount of books Ashley reads = 4(6) + 3
= 24 + 3
= 27
