Question

What is the inverse of y = x2 + 16

Answer 1

`{y}^( - 1) = √(x - 16)`

Explanation:

• To find the inverse of this function, we make "x" the subject of the equation .
• 
  `y = {x}^(2) + 16 \\ {x}^(2) = y - 16 \\ x = √(y - 16)`
• then we interchange "y" and "x" .
• 
  `hence \: the \: inverse \: is \\ {y}^( - 1) = √(x - 16)`
