Answer:
No, it is not a one-to-one function.
Step-by-step explanation:
A one-to-one function means a value of y will only exist one value of x. This means that a value of y will only have one value of x.
An example of one-to-one function is an odd-degree polynomial such as linear function.
An example of <u>non</u> one-to-one function is a parabola since a value of y exists two values of x.
From the question, this function represents a graph of half circle with radius equal to
. (The graph has been attached below for visual reference.)
There's also <u>a way to determine whether if a function is one-to-one</u> or not. This can be done by drawing a horizontal line.
- If a horizontal line and a graph have <u>one</u> common point then it's a one-to-one function
- Otherwise (having more than one common points), a function is not a one-to-one.
From the graph and a horizontal line, both have two common points. Therefore, the function is not a one-to-one function.

Multiply the number together ....

Answer:
point f is in quadrant 3 . . .
There are 312 books in total.
Let 'x' represent the number of FICTION books.
There are 11x NONFICTION books and 1x FICTION books.
1x+11x=312
12x=312
Now divide 12x by 12 and 312 by 12 (whatever you do to one side of the equals sign you have to do to the other)
Once you do that you will get 1x=26
This means you have 26 fiction books. Now, you have 11 times as many nonfiction books so 26x11=286
This means you have 286 nonfiction books
To check your answer add 286 and 26 to make sure it adds to 312.
