Which equation is the inverse of y = x2 + 16? O y = x2 – 16
y=+√x - 16
y=+NX-16
y = x2 - 4

Hi there!

To solve for the inverse, swap the x and y variables:

x = y² + 16

Isolate for y by subtracting both sides by 16:

x - 16 = y²

Square root both sides:

√(x - 16) = y

Add the plus/minus sign:

y = ±√(x - 16)
