Answer:
f(x)=(x-2)(x+2)(x-5)
Step-by-step explanation:
f(x)=x³-5x²+4x-20                 1. Just group randomly
f(x)=x²(x-5)+4(x-5)                2. Factor the groupings
f(x)=(x²+4)(x-5)                      
<u>f(x)=(x-2)(x+2)(x-5)</u>                3. Factor the difference of two squares

Answers:
f(-3) = -1
f(-1) = 2
f(3) = 5
======================================
Explanations:
Draw a vertical line through -3 on the x axis. Make sure this vertical line crosses the orange graph. Mark this point of intersection and then draw a horizontal line from this point to the y axis. You should find that it touches -1 on the y axis. Check out the attached image to see this process in action. 
Those steps basically say that x = -3 leads to y = -1. Since y = f(x), this means f(-3) = -1
Through similar steps, you should find that f(-1) = 2 and f(3) = 5
Note that the open hole/circle does not count. So if you land on an open hole, just keep going until you hit a closed circle on the other piece of the graph. 
 
        
                    
             
        
        
        
The absolute value is |5| = -5
