Solve: $\frac{2}{x-2}-\frac{1}{x+1}=\frac{2}{x^2-x-2}$  

• x = 2

• x = -2

• x = 6

• x = 3

What is the inverse of the given coordinates: (1, 2) (3, 8) (-3, 6)

• (1, 2) (3, 8) (-3, 6)
• (1, 2) (8, 3) (-3, 6)
• (-1, -2) (-3, -8) (3, -6)
• (2, 1) (8, 3) (6, -3)

Find the inverse of f(x) = -4x - 12

• f^-1(x) = 4x - 3
• f^-1(x) = -1/4x - 3
• f^-1(x) = 1/4x + 3
• f^-1(x) = -4x - 3

Was the inverse function found correctly?

• no,
• yes
