Answer:
The domain is (-∞ , ∞)
The domain is continuous
Step-by-step explanation:
Here, we want to identify the domain of the linear function
The domain in this case can be represented by the set of all real numbers.
When we talk of the domain of a function, we are simply referring to the the range of values between the smallest value on the x-axis and the largest number on the x-axis
Hence, mathematically, we are simply considering the smallest value of b up to the largest value of b in this case. Where b simply represents the number of books
Thus, the domain here will be (-∞ , ∞)
On if the domain is discrete or continuous, we can see that the domain is continuous.
The domain is continuous simply because, the domain we have contains all the values and not some in the set of real numbers. If it had contain only some, then it would have been discrete. But since it contains all, it is continuous
Answer:
![y = 3(x +21)](https://tex.z-dn.net/?f=y%20%3D%203%28x%20%2B21%29)
Step-by-step explanation:
Find the inverse this equation:
![f(x) = (\frac{1}{3}x) - 7](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%28%5Cfrac%7B1%7D%7B3%7Dx%29%20-%207)
-Take the variable
for
, because both
![y = (\frac{1}{3}x) - 7](https://tex.z-dn.net/?f=y%20%3D%20%28%5Cfrac%7B1%7D%7B3%7Dx%29%20-%207)
-Switch both variable
and
:
![y = (\frac{1}{3}x) - 7](https://tex.z-dn.net/?f=y%20%3D%20%28%5Cfrac%7B1%7D%7B3%7Dx%29%20-%207)
![x = (\frac{1}{3}y) - 7](https://tex.z-dn.net/?f=x%20%3D%20%28%5Cfrac%7B1%7D%7B3%7Dy%29%20-%207)
-Solve for
:
![x = (\frac{1}{3}y) - 7](https://tex.z-dn.net/?f=x%20%3D%20%28%5Cfrac%7B1%7D%7B3%7Dy%29%20-%207)
-Switch sides:
![\frac{1}{3}y - 7 = x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dy%20-%207%20%3D%20x)
-Add both side of the equation by
:
![\frac{1}{3}y - 7 + 7 = x + 7](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dy%20-%207%20%2B%207%20%20%3D%20x%20%2B%207)
![\frac{1}{3}y = x + 7](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dy%20%3D%20x%20%2B%207)
-Multiply both sides by
:
![\frac{\frac{1}{3}y}{\frac{1}{3} } = \frac{x + 7}{\frac{1}{3} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B1%7D%7B3%7Dy%7D%7B%5Cfrac%7B1%7D%7B3%7D%20%7D%20%20%3D%20%5Cfrac%7Bx%20%2B%207%7D%7B%5Cfrac%7B1%7D%7B3%7D%20%7D)
![y = \frac{x + 7}{\frac{1}{3} }](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7Bx%20%2B%207%7D%7B%5Cfrac%7B1%7D%7B3%7D%20%7D)
-Divide
by multiplying by ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
![y = \frac{x + 7}{\frac{1}{3} }](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7Bx%20%2B%207%7D%7B%5Cfrac%7B1%7D%7B3%7D%20%7D)
![y = 3(x +21)](https://tex.z-dn.net/?f=y%20%3D%203%28x%20%2B21%29)
Therefore, the answer is
.
