Solution 1

To find the inverse of the function f(x) = -x^2 - 4, we need to switch the roles of x and f(x) and solve for x.

Step 1: Replace f(x) with y. y = -x^2 - 4

Step 2: Swap x and y. x = -y^2 - 4

Step 3: Solve for y. x + 4 = -y^2 y^2 = -x - 4

Step 4: Take the square root of both sides. y = ±√(-x - 4)
