Question

Which equation is the inverse of y = x2 – 36?

= I Vx+6

x+ 3B

y=+*+36

y=+

V=+ VX +36

Answer 1

y =
`√(x + 36)`

Step-by-step explanation:

y =
`x^(2)` - 36

to find the inverse of the above equation, we solve as follows.

first, we swap places for the x and the y

x =
`y^(2)` - 36

next, we solve for y, first by adding 36 to both sides of the equation

x + 36 =
`y^(2)` - 36 + 36

x + 36 =
`y^(2)`

find the square root of both sides of the equation

`√(x + 36)` =
`\sqrt{y^(2) }`

y =
`√(x + 36)`
