Which is the graph of f(x)=√x?

Answer:

Given function:

f(x)=\sqrt{x}

Replace f(x) for y:

\implies y=\sqrt{x}

Square both sides:

\implies y^2=x

This is a <u>sideways parabola</u> that opens to the <em>right</em>, with an axis of symmetry at y = 0.  (Refer to attachment 1)

If we square root this again, we get:

\implies \sqrt{y^2}=\sqrt{x}

\implies y=\pm\sqrt{x}

So y=\sqrt{x} is the part of the parabola in quadrant I → (x, y)

And y=-\sqrt{x} is the part of the parabola in quadrant IV → (x, -y)

(Refer to attachment 2)

Therefore, the graph of the given function is <u>attachment 3</u>.

What is the transformation of C(9, 3) when dilated with a scale factor of 1/3,
Harman [31]

The transformation of C(9, 3) when dilated with a scale factor of 1/3, using the point (3, 6) as the center of dilation would be an option B: C'(3,1).

<h3>What is Dilation transformation?</h3>

A dilation transformation is a transformation that changes the size of the original figure but the shape remains unchanged.

If any figure is dilated by a scale factor k with the center of dilation as the origin.

Then the change of transformation in each of the vertices of the figure is given:

(x,y) → (kx, ky)

It is given a point C which is located at C(9,3).

Hence, here k=3

We get:

C(9,3) → C'(9×3,3×3)

C(9,3) → C'(27,9) = C'(3,1)

Hence, the transformation of C(9, 3) when dilated with a scale factor of 1/3, using the point (3, 6) as the center of dilation would be an option B: C'(3,1).

Solve the equation 5n+7=21
Simora [160]

Answer:

Hi there, I believe the answer to this equation is: 2.8

Step-by-step explanation:

Subtract 7 on both sides so

5n+7=21-7

you are left with 5n=14 you need to get n by itself so divide 5 on both sides.

5n/5 = 14/5

n=2.8

Hope this is correct :)

Have a great day

4 - x + <img src="https://tex.z-dn.net/?f=6%5E%7B2%7D" id="TexFormula1" title="6^{2}" alt="6^{2}" align="absmiddle" class="latex
Lemur [1.5K]

Answer:

x ≤ 19

Step-by-step explanation:

The instructions here are probably "solve for x."  Please include them.

4 - x + 6^2 ≥  21

becomes 4 - x + 36 ≥  21

Now combine like terms.  4 and 36 combine to 40:  40 - x ≥ 21, and so:

19 - x ≥ 0

Adding x to both sies results in

x ≤ 19

Please, include the instructions when you post a question.  Thanks.
