Find the Domain to my screenshot

The Domain is {1,2}

Step-by-step explanation:

To understand the problem very easily, take a grid sheet and draw a quadran. Then place the points of the cords.

The first point at the upper limit is located at -2 relative to the x axis and +4 relative to the y axis. the second at -1 and +3, the third 0 and +2, the fourth at +1 and +1 and the last at +2 and 0.

All you have to do is join the points with a rule to get exactly the same line. Simple, right?

But to solve this kind of problem, you must understand what a domain is and its corollary, storage. To this end, we have provided you with a very explanatory and easy to understand document if you read it several times.

So, as you will see in the attached document, the elements of the domain and storage must always be positive numbers.

Thus, the Domain of f(x)= {1, ∞ } and thus range = {0, ∞ }.

So here the domain is [1,2] and the Storage is {0,1,2,3,4}.

.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
