 Answer:
Step-by-step explanation:
1.  She omitted the 0 from the minuend, entering 24.59 instead of 204.59
2. She misplaced the decimal point of the minuend, entering 93.64 instead of 936.4
3. She typed 4 instead of 5 in the minuend, entering 46.3 instead of 56.3
 
        
             
        
        
        
f(x) = -5x - 15 
Let y = f(x) 
y = -5x - 15 
Switch the x and y places, and solve for y: 
x = -5y - 15 
-5y = x + 15 
y = (x + 15)/-5 
y = -(x/5) - 3 
So the inverse of : f(x) = -5x - 15 is 
-x/5 - 3
