Step-by-step explanation:
We have that point A is at 3.
This is 3 units to the right of 0 on the number line.
The point that is opposite of A should be 3 units to the left of 0.
That point will be at -3.
Therefore you have to choose the point that is on -3.
It should be similar to one in the attachment.
Answer:
Domain: ![\mathbb{R}](https://tex.z-dn.net/?f=%5Cmathbb%7BR%7D)
Inverse: ![f^{-1}(x) = -x + 5](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20-x%20%2B%205)
Step-by-step explanation:
Since this is a linear function, the domain and range is simply the set of real numbers.
The inverse is obtain by switching the places of x and y, then solving for y.
Here,
y = -x + 5
So switching x and y,
x = -y + 5
Solving for y again,
y = -x + 5
Thus,
![f^{-1}(x) = -x + 5](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20-x%20%2B%205)
Answer:
The price per inch is $0.26.
Step-by-step explanation:
There are 12 inches in 1 foot.
First, we need to calculate what the cost is per foot.
18.72 / 6 = 3.12
From this answer, we have to divide by 12 to calculate what the price is per inch.
3.12 / 12 = 0.26
