Find the equation of the inverse of
y = (x - 1)² + 7.
cc ccA.
cy = -
x - 7 + 1 only
B.
cy =
x - 7 + 1 only
C.
cy =
x + 1 - 7 only
D.
cy = ±
x - 7 + 1
c
D
Step 1: y = (x - 1)² + 7
Step 2: x = (y - 1)² + 7[Interchange x and y.]
Step 3: x - 7 = (y - 1)²[Subtracting 7 from the two sides of the equation.]
Step 4: y - 1 = ± x - 7[Find the square root of both sides.]
Step 5: y = ± x - 7 + 1[Solve for y.]
Step 6: So, the equation of the inverse is y = ± x - 7 + 1.
