here u go! i hope this is correct :)
Is this a function and what's the domain and range. thanks!

This is not a function. Why not? Because it fails the vertical line test. The input x = 3 leads to more than one output (eg: y = 1, y = 2, y = 3). A function is only possible if each input leads to exactly one output.
Domain = {3} so basically x is only allowed to be x = 3.
Range = set of y values such that y is between 1 and 5 (including both endpoints. As a compound inequality, the range is written as

Step-by-step explanation:
<u>Solving Equations</u>
We have the expression:
And it's required to make y the subject.
It can be done by isolating y on the left side of the equation and the rest of the expression on the right side.
The first step is removing the denominator by multiplying both sides by y-3:
Simplifying the right side:
Remove the parentheses:
Move the y's to the left side and the rest of the expression to the right side:
Factor out y:
Divide by x-1:
