**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**.

<em>* The red graph represents the given function while blue graph is a horizontal line determining a one-to-one function or not *</em>

Okay i'm confused on the question but i do know the answer of the diameter

if that help the diameter would be d=5.09cm

i hope this helps

Step 2: She did not simplify under the square root correctly

under the square root:

(-6)^2 =36

and -4(5)(-8) =160

therefore under the square root it needs to be square root of 36+160 which is square root of 196.

That answer is 14 when square rooted

**Answer:**

The correct answer is 2.

**Step-by-step explanation:**

We simplify it until it reaches an answer that can no longer be simplified
