The inverse of the equation y = x² - 4, x≤ 0 is 
<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

Hence, the inverse of the equation y = x² - 4, x≤ 0 is
