Identify the percent of change as an increase or a decrease.

1/4 to 1/2

Increase.

1/4 can be translated to 25%

1/2 can be translated to 50%

25% to 50% is an increase.

Increase because 1/4 can be known as 25 percent and 1/2 known as 50 percent

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
