Answer:
y = sqrt(16 - (x - 2)^2) - 1 or y = -sqrt(16 - (x - 2)^2) - 1
Step-by-step explanation:
Solve for y:
(x - 2)^2 + (y + 1)^2 = 16
Subtract (x - 2)^2 from both sides:
(y + 1)^2 = 16 - (x - 2)^2
Take the square root of both sides:
y + 1 = sqrt(16 - (x - 2)^2) or y + 1 = -sqrt(16 - (x - 2)^2)
Subtract 1 from both sides:
y = sqrt(16 - (x - 2)^2) - 1 or y + 1 = -sqrt(16 - (x - 2)^2)
Subtract 1 from both sides:
Answer: y = sqrt(16 - (x - 2)^2) - 1 or y = -sqrt(16 - (x - 2)^2) - 1
