Which function is the inverse f(x)=-5x-4
Kay [80]

Answer:

f⁻¹(x) = -(x+4) / 5

Step-by-step explanation:

Given function is :

f(x) = -5x-4

We have to find the inverse of given function.

Step 1.  Put y = f(x) in given function

y = -5x-4

Step 2. Add 4 to both sides of above equation

y+4= -5x-4+4

y+4 = -5x

Step 3.Divide by -5 to both sides of above equation

y+4 / (-5) = -5x / (-5)

-(y+4) / 5 = x

Step 4 . Swap sides

x = -(y+4) / 5

Step 5. Put x = f⁻¹(y) in above equation

f⁻¹(y) = -(y+4) / 5

Step 6. replace y with x

f⁻¹(x) = -(x+4) / 5 which is the inverse of f(x) = -5x-4.
