Question

What is the inverse of y = x2 + 16

Answer 1

Y=x2-16
I’m not sure if I’m right or not

Answer 2

Answer:

${y}^{ - 1} = \sqrt{x - 16}$

Step-by-step explanation:

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