Given the parent function f(x) = x², define the function g(x) that

Bas_tet [7]

Answer:

Part 1) $g(x)=-x^{2}$

Part 2) $g(x)=(x+3)^{2}$

Part 3) $g(x)=x^{2}+7$

Step-by-step explanation:

we have

The parent function is $f(x)=x^{2}$

This is a vertical parabola open upward with vertex at origin (0,0)

Part 1) Reflection over the x-axis

The rule of the reflection across the x=axis is equal to

(x,y) ------> (x,-y)

f(x) -----> g(x)

The function g(x) will be

$g(x)=-x^{2}$

Part 2) Horizontal shift left 3 units

The rule of the translation is

(x,y) ------> (x-3,-y)

f(x) -----> g(x)

The function g(x) will be

$g(x)=(x+3)^{2}$

Part 3) Vertical shift up 7 units

The rule of the translation is

(x,y) ------> (x,y+7)

f(x) -----> g(x)

The function g(x) will be

$g(x)=x^{2}+7$

The Carousel at Carowinds has 4 rings of horses. Fred is riding on the inner ring, which has a radius of 7 feet. Juan is riding

nikdorinn [45]

Answer:

Juan travel 31.4 feet farther than Fred in one rotation.

Step-by-step explanation:

In this problem we need to determine the change in linear position of Fred and Juan, whose formula is:

$s=\theta \cdot r$ (Eq. 1)

Where:

$r$ - Radius, measured in feet.

$\theta$ - Angular arch, measured in radians.

$s$ - Change in linear position, measured in feet.

If both makes one rotation in the carousel, we obtain the change in linear position of each player:

Fred ( $r = 7\,ft$ , $\theta = 2\pi$ )

$s= 2\pi\cdot (7\,ft)$

$s = (3.14)\cdot (7\,ft)$

$s = 21.98\,ft$

Juan ( $r = 17\,ft$ , $\theta = 2\pi$ )

$s= 2\pi\cdot (17\,ft)$

$s = (3.14)\cdot (17\,ft)$

$s = 53.38\,ft$

And the difference between both travelled distances is:

$\Delta s = 53.38\,ft-21.98\,ft$

$\Delta s = 31.4\,ft$

Juan travel 31.4 feet farther than Fred in one rotation.
