Which statement best describes the function below?
marta [7]
<h2>Answer:</h2>

A. It is a many-to-one function.

<h2>Step-by-step explanation:</h2>

Hello! It will be a pleasure to help to figure out what's the correct answer to this problem. First of all, we have the following function:

f(x) = 2x^3 + 2x^2-x

When plotting this function, we get the red graph of the function shown below. So let's solve this as follows:

<h3>A. It is a many-to-one function.</h3>

True

A function is said to be many-to-one there are values of the dependent variable (y-values) that corresponds to more than one value of the independent variable (x-values). To test this, we need to use the Horizontal Line Test. So let's take the horizontal line y=0.5, and you can see from the first figure below that y=0.5 is mapped onto x=-1.241 \ x=-0.344 \ and \ x=0.585. so this is a many-to-one function.

<h3>B. It is a one-to-one function.</h3><h3>False</h3>

Since this is a many-to-one function, it can't be a one-to-one function.

<h3>C. It is not a function.</h3>

False

Indeed, this is a function

<h3>D. It fails the vertical line test.​</h3>

False

It passes the vertical line test because any vertical line can intersect the graph of the function at most once. An example of this is shown in the second figure below.

What figure is described below?<br><br> the points in space equidistant from the endpoints of PQ.
skelet666 [1.2K]
The question is slightly weird.

You have a piece of line, and its ends are 'P' and 'Q'.

All of the points on the paper that are the same distance
from 'P' and 'Q' are the points that form the line that bisects
segment-PQ and is perpendicular to it.
Other words:  The line that is perpendicular to PQ at its mid-point.
Other words:  The perpendicular bisector of segment PQ.

All of the points in space that are the same distance from
'P' and 'Q' are the points that form the plane perpendicular
to segment PQ at its mid-point.

Find the volume of the hemisphere with a radius of 7 inches. Round your answer to the nearest tenth.
EleoNora [17]

Answer:

The formula for the volume of a sphere is:

Sphere Volume   =   4/3 • π • r^3

Sphere Volume   =   4/3 • π • 7^3

Sphere Volume   =   4/3 • π • 343

Sphere Volume   =   1,436.7550402417 cubic inches
