Answer:
See options below. No answer choice given.
Step-by-step explanation:
The graph of the function is below. What can be said about the function is the following:
- Roots are -2 and -6.
- Factors are (x+2) and (x+6)
- X-intercepts are (-2,0) and (-6,0)
- Y -intercept is (0,-12)
- Parabola is concave down due to negative leading coefficient
- Vertex is at (-4,4)
- Axis of Symmetry is x=-4
- Its a quadratic which has a parabola as its graph
 
        
                    
             
        
        
        
Answer:
45 min
Step-by-step explanation:
Here,
the we take the work as W and Alan's speed as A and Zack's speed as Z.
A = 2Z
W = 30 ( A+Z)
if the time for Alan to done cleaning alone is t then t = W ÷ A
t = ( 30 (A+(A÷2)))÷ A
t = 45 min
I am done .
