Find the inverse function to y=x^2 +12

Hi Sami

y = x² + 12

The first thing we would do is make x the subject of the equation

x² = y - 12

Lets take the square root of both sides of the equation

x = ±√(y - 12)

Its a ± because it can be a + square or a - square

Now we can switch x and y to get the inverse function

x = ±√(y - 12) becomes

y = ±√(x - 12)

So the inverse function is y = ±√(x - 12)

May your day be touched with sunshine.

y=x^2 +12
swap y and x and solve for y
x = y² + 12
y² = x – 12
y = √(x – 12)
