We need to find f(1)
f(1) means x=1
Now we look at the three inequalities and choose the one where x=1 satisfies
x<=-1 , -1<x<1 and x>=1
x=1 satisfies the inequality x>=1
so we use the third function to find f(1)
We plug in 1 for x and find f(1)
= 2 + 3 = 5
f(1) = 5

Answer:
<u>200 additional gallons of water are used when 40 people take a bath instead of a shower</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of water used when we take a bath = 20 gallons
Amount of water used when we take a shower = 15 gallons
Number of people who wants to take a bath = 40
2. How much extra water is used?
Extra water is used = Number of people * (Amount of water used when we take a bath - Amount of water used when we take a shower)
Replacing with the real values, we have:
Extra water is used = 40 * (20 - 15)
Extra water is used = 40 * 5 = 200 gallons
Am not sure but i think its 9m^4-49n^6 hope it helps :)
