x=-1, x=3, x=4
Step-by-step explanation:
1. Substitute 0 for f(x)
0=(x+1)(x-3)(x-4)
2. Set each set of parenthesis equal to 0

x=-1, x=3, x=4
Answer: The seasonal relatives is calculated are as follows:
Step-by-step explanation:
Given that,
restaurant only open from Wednesday to Saturday,
- 29 percent of its business on Friday
- 31 percent on Saturday night
- 21 percent on Thursday night.
∴ The remaining 19% of its business he does on Wednesday
Now, suppose that total production of sales in a given week be 'y'
So, average sales in a week = 
If we assume that y = 1
hence, average sales in a week = 
= 0.25
Now, we have to calculate the seasonal relatives,
that is,
= 
Wednesday:
= 
= 0.76
Thursday:
= 
= 0.84
Friday:
= 
= 1.16
Saturday:
= 
= 1.24
