The function I = 19n is a linear function
The reasonable domain of the function is [0,21]
<h3>How to determine the domain?</h3>
The function is given as:
I = 19n
The smallest value of n is 0 i.e. the smallest number of ticket sold is 0
The maximum capacity is 400.
So, we have:
19n = 400
Divide both sides by 19
n = 21.05
Remove the decimals
n = 21
Hence, the reasonable domain of the function is [0,21]

The answer is one. do you need an explanation or no
Answer:
(0, 22)
Step-by-step explanation:
So you have the equation:
![y-1=-7(x-3)](https://tex.z-dn.net/?f=y-1%3D-7%28x-3%29)
So first let's define what the "y-intercept" is. The y-intercept, of a line is like the name implies, when the line intercepts or "passes" the y-axis. And if you were to take any point on the y-axis, the y-value may vary, but there is one value that doesn't change, and that's the x-value. the x-value is always going to be zero, no matter where you are on the y-axis. So to find the y-intercept simple plug 0 in as x. This gives you the equation:
![y-1 = -7(0-3)](https://tex.z-dn.net/?f=y-1%20%3D%20-7%280-3%29)
![y-1 = -7(-3)](https://tex.z-dn.net/?f=y-1%20%3D%20-7%28-3%29)
![y-1=21](https://tex.z-dn.net/?f=y-1%3D21)
![y=22](https://tex.z-dn.net/?f=y%3D22)
So the y-intercept is at (0, 22)
