Is This A Quadratic Function? Why Or Why Not?

Answers

Answer 1

Answer:

Not a quadratic function.

Step-by-step explanation:

Definitions

A function is a relation wherein each input or x-value corresponds exactly to an output or y-value.  In other words, a relation is a function if there are no repeating x-values.  

Vertical Line Test :

A way to determine whether a given graph represents a function is to perform the Vertical Line Test.  Using the Vertical Line Test, we must draw vertical lines across the graph.  If each of the vertical lines drawn intersects the graph at exactly one point, then the relation is a function.  

⇒  The attached screenshot shows that the given graph fails the Vertical Line Test, as each vertical line drawn intersects the graph more than once. This means that those x-values correspond to more than one y-value. Specifically, x = 1 corresponds to the following y-values: y = -1 and y = 1.   Hence, the given horizontal parabola is not a quadratic function.

Horizontal Parabola: Not a Function      

The given graph represents a horizontal (or sideways) parabola.

The vertex form of the horizontal parabola is: x = a(y - k)² + h.  

where:

a = Determines the direction of the graph's opening.

a > 0, the graph of the parabola opens to the right.a < 0, the graph of the horizontal parabola opens to the left

y = k is the horizontal axis of symmetry

k = determines the vertical translation of the graph

h = determines the horizontal translation of the graph

Equation of the Horizontal Parabola in Vertex Form:

The vertex of the given graph occurs at the point of origin, (0, 0).

Let's use one of the given points on the graph, (1, 1), and substitute these values into the vertex form to solve for a :

x = a(y - k)² + h

1 = a(1 - 0)² + 0

1 = a( 1 )²

1 = a

Equation of the given horizontal parabola in vertex form:  

      ⇒     x = (y - 0)² + 0  or  x = y²

It is evident that in the vertex form of a horizontal parabola, the variable, y, is squared.

This implies that each x-values on the graph have more than one corresponding y-values:

                          x = 1 has two y-values: y = -1, and y = 1.

                           x = 4 has two y-values: y = -2, and y = 2.

Thus, by definition of function, the given horizontal parabola is not a quadratic function, as it fails the vertical line test.

Find the value of x.

Answers

Answer:

11

Step-by-step explanation:

Arc YZ and angle YXZ must add up to 180. You can review your notes, and you will probably find an identity that relates to this. But I will prove this using quadrilaterals, mainly, well, because I forgot what the identity was.

Lets call the center of the circle O. Angles XYO and XZO must be 90 degrees since they are tangent to the circle. These angles add up to 180, leaving the two remaining angles, who also must add up to 180. Therefore, the angle YOZ, and YXZ, must add up to 180. Note that angle YOZ is equal to arc YZ.

In our case, angle YOZ is 125 degrees given by the arc YZ, and the angle of YXZ is 6x-11. We can set up an equation like this:

YXZ+YOZ=180

6x-11+125=180

Simplify

6x+114=180

Solve

6x=66

x=11

Therefore, our value of x is 11 and the angle YXZ is 55 degrees.

Calculate the measure of angle ADB if angle ACB is 50 degrees.

Answers

Answer:

ADB=50°

Step-by-step explanation:

Angles subtended by the same segment are equal

Therefore,the angle ∠[tex]ADB=40[/tex] degree.

What are the angles?

An angle is a form of geometrical shape, that is constructed by joining two rays to each other at their end-points.

Here given that ∠[tex]ACB=50[/tex] degree and we know alternates angles are equal so ∠[tex]CAD=50[/tex] degree.

And [tex]AD[/tex] is parallel to [tex]BC[/tex].

Therefore, the diagonals of a rhombus are at right angled.

So, ∠[tex]AOD=90[/tex] degree

Now, In Δ[tex]AOD[/tex],

∠[tex]ADO+[/tex]∠[tex]DAO+[/tex]∠[tex]AOD=180[/tex] degree

∠[tex]ADO+50+90=180[/tex]

∠[tex]ADO=+140=180[/tex]

∠[tex]ADO=180-140[/tex]

∠[tex]ADO=40[/tex] degree

or

∠[tex]ADB=40[/tex] degree.

Hence, the angle ∠[tex]ADB=40[/tex] degree.
