What is the inverse of the equation y=x²-4, x≤ 0​
Lina20 [59]

The inverse of the equation y = x² - 4, x≤ 0​ is y = \sqrt{x + 4

<h3>How to determine the inverse of the equation?</h3>

The equation is given as:

y = x² - 4, x≤ 0​

Swap the x and y values

x = y² - 4

Add 4 to both sides

y² = x + 4

Take the square root of both sides

y = \sqrt{x + 4

Hence, the inverse of the equation y = x² - 4, x≤ 0​ is y = \sqrt{x + 4
