Find the inverse of f(x) = x² - 5

• f^-1(x) = √(x) + 5
• f^-1(x) = ∛(x-5)
• f^-1(x) =√(x+5)
• f^-1(x) = x² - 5

Find the inverse of the function.

• f^-1 = (x + 3)² − 4

• f^-1 = (x − 4)² + 3

• f^-1 = (x + 3)² − 4
• Inverse does not exist

Find the inverse of the function

• f^-1 = x³ − 5

• f^-1 = x³ + 5

• f^-1 = x³ + 5
• Inverse does not exist

Find the inverse of the function

• f^-1 = ((x − 1) / 2)³ − 4

• f^-1 = ((x + 4) / 2)³ + 1
• f^-1 = ((x − 4) / 2)³ − 1
• Inverse does not exist
