Which equation is the inverse of y = x2 – 36? y = plus-or-minus startroot x endroot 6 y = plus-or-minus startroot x 36 endroot y
svet-max [94.6K]

The inverse of the given function is expressed as y =  ±√x + 38

<h3>Inverse of an equation</h3>

Given the equation below expressed as:

y = x²  - 36

Replace y with x

x = y² - 38

Add 38 to both sides of the equation

x + 38 = y² - 38 + 38
y² = x + 38

Take the square root of both sides

√y² = ±√x + 38

y =  ±√x + 38

Hence the inverse of the given function is expressed as y =  ±√x + 38
