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.
1 treat is 19 cents so you multiply 250 by 0.19 and you get 47.50 then take the $19.95 the amount for a package of treats and minus it from 47.50 and you save $27.55
