A graph of a quadratic function y = f(x) is shown below.

spin [16.1K]

We are given a graph of a quadratic function y = f(x) .

We need to find the solution set of the given graph of a quadratic function .

Note: Solution of a function the values of x-coordinates, where graph cut the x-axis.

For the shown graph, we can see that parabola in the graph doesn't cut the x-axis at any point.

It cuts only y-axis.

Because solution of a graph is only the values of x-coordinates, where graph cut the x-axis. Therefore, there would not by any solution of the quadratic function y = f(x).

<h3>So, the correct option is 2nd option :∅.</h3>

H = {(2, 5), (3, 5), (4, 5), (5, 5), (6, 5)} Is H a function and why?.

Answer:

Yes, each x-value has a unique y-value.

Step-by-step explanation:

This is a function because each x-value has its own y-value. If this is not the case then it is not a function, because then, two points with the same x-value and different y-values would fail the VLT.

Your graph does not have overlaps and each x-value has a unique y-value

VLT

The vertical line test (VLT) is a simple method that mathematicians made because they were lazy to make a table of values and find duplicates.

Passing the VLT means that if you drew a vertical line anywhere on the graph, it would only go through one point.
Failing the VLT would mean that the vertical line

A quick way to check if it is a function is by looking for duplicates of x-values and check that the duplicates have the same y-value.

I need help knowing how to do the problem

Vlad1618 [11]

Volume of a cone = pi * r² * (h/3)

If your diameter is 2, then take half of that for the radius; your radius is 1

Now plug in your given info:

V = pi * (1)² * (7/3)
= pi * 1 * (7/3)
= 7pi / 3

V ≈ 7.3304

Your answer is option D.
