A function can be represented by equations and tables
- 4 users are logged in by 9am
- The domain is [3,23] and the range of the function is [3,4]
<h3>The number of users at 9am</h3>
The function is given as:
At 9am, x = 9.
So, we have:
Simplify
Approximate
Hence, 4 users are logged in by 9am
<h3>The domain</h3>
Set the radical to 0
Solve for x
The maximum time after midnight is 23 hours.
So, the domain is [3,23]
<h3>The range</h3>
When x = 3, we have:
When x = 23, we have:
So, the range of the function is [3,4]

The second one is the only positive besides 4th but the second and first are the only 1861 so ide have to say the second one
Answer:
2/5 of an inch per minute
Step-by-step explanation:
You can set up the rate as 
. From here to find the amount of rain per minute, just multiply the numerator and denominator by 6/5 (The reciprocal of 5/6, so you can have one minute and see how much rains fills up in that time.)
You end with 2/5 of and inch per minute
Answer:
x= 3, x=5 or x^2 + 8x + 15
Step-by-step explanation:
(x+3)(x+5)
(x*x)(x*5)(3*x)(3*5)
x^2 + 5x + 3x + 15
x^2 + 8x + 15
x+3 = 0 x+5 = 0
-3 -3 -5 -5
x= -3 x= -5
