The graph of g(x) is a translation of the function f(x) = x2. The vertex of g(x) is located 5 units above and 7 units to the rig

ht of the vertex of f(x). Which equation represents g(x)?
g(x) = (x + 7)2 + 5
g(x) = (x – 7)2 + 5
g(x) = (x + 5)2 + 7
g(x) = (x – 5)2 + 7

we know that

The graph of g(x) is a translation of the function f(x)

so

f(x)=x^{2}

the vertex of f(x) is the point (0,0)

the vertex of g(x) is located 5 units above and 7 units to the right of the vertex of f(x)

The rule of the translation is

(x,y)--------> (x+7,y+5)

<u>Find the vertex of the function g(x)</u>

(0+7,0+5)=(7,5)

the vertex of g(x) is the point (7,5)

the equation of the function g(x) in the vertex form is equal to

g(x)=(x-h)^{2} +k

where

(h,k) is the vertex

substitute the value of the vertex in the equation

g(x)=(x-7)^{2} +5

<u>the answer is</u>

g(x)=(x-7)^{2}+5

Answer: See below

Step-by-step explanation:

h\:\circ \:g=h\left(g\left(x\right)\right)

=5\left(7x^2-4x-3\right)^2-12\left(7x^2-4x-3\right)

=5\left(7x^2-4x-3\right)\left(7x^2-4x-3\right)-12\left(7x^2-4x-3\right)

=245x^4-280x^3-130x^2+120x+45-84x^2+48x+36

Simplify:

=245x^4-280x^3-214x^2+168x+81

Jackson's mom limits the amount of time he is allowed to play video games. after Jackson plays for 9 minutes, his mom tells him
ValentinkaMS [17]
First off Jackson's mom sucks for limiting game time and second of the answer is 30 minutes. If 9 is 30 percent that means 3 is 10 percent. 3 times 10 is 30. So 30 minutes
