Which represents the reflection of f(x)=sqrt x over the y axis

zloy xaker [14]

reflection of $f(x)=\sqrt{x}$ over the y axis we get $g(x)=\sqrt{-x}$

Step-by-step explanation:

We need to find the reflection of f(x)=sqrt x over the y axis

So, reflection over y- axis

If the function f(x) is transformed over y-axis then the new function g(x) will be $g(x)= f(-x)$

So, finding reflection of $f(x)=\sqrt{x}$ over the y axis we get:

$g(x)=\sqrt{-x}$

So, reflection of $f(x)=\sqrt{x}$ over the y axis we get $g(x)=\sqrt{-x}$

Thirty percent of the fifth grade students in a large school district read below grade level. The distribution of sample proport

fredd [130]

Answer: 0.9088

Step-by-step explanation:

Given : $\mu=0.30$

$\sigma=0.045$

Let x be a random available that represents the proportion of students that reads below grade level .

Using $z=\dfrac{x-\mu}{\sigma$ , for x= 0.36 , we have

$z=\dfrac{0.36-0.30}{0.045}=1.33333$

Using standard normal z-value table,

P-value $= P($

$P(z$ [Rounded yo the nearest 4 decimal places.]

Hence, the probability that a second sample would be selected with a proportion less than 0.36 = 0.9088

Answer:

$4x^2(x-2)(x+6)$

Step-by-step explanation:

Factor $4x^2$

$4x^2(x^2)+4x^2(4x)-4x^2(-12)$

$4x^2(x^2+4x-12)$

$4x^2(x-2)(x+6)$

good luck, hope this helps :)
