A. 3x2y2 + 4xy2 + 3x2 + 3y2 – 3
B. 80272 + 2xy2 – 4y2 + 4
C. 97272 + 4ry2 – 3
D. 3.12y2 + 6ry2 + 6x2 + 3

Step-by-step explanation:

The step by step explanation in in the picture below

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 would be 0.18 because when the other choices are converted they equal those two numbers.   hope this !
