Select all the relations that represent a function. A. (3,2), (2,1), (3,9), (4,7)
B. (1,7), (2,2), (3,5), (4,8)
C. (2,6), (6,5), (3,5), (4,8)
D. (4,3), (3,3), (2,3), (1,3)
E. (2,2), (2,5), (2,1), (2,3)

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.

it could be 242. irdk i tried my best
