Answer:
f(0) is approximately equal to 7.07
Step-by-step explanation:
All you need to do here is substitute a zero wherever you see an x in the equation, giving us:
Let
x-----> the time in minutes
y------> the number of gallons of water
we know that
the unit rates is equal to

then
<u>Problem</u>
1) How many gallons of water will Elyse use in three minutes in the shower?
For x=3 minutes
substitute in the equation above
<u>the answer is</u>
