Question

Hey, can someone help me:
what is the domain and range of each of the following? use interval notation
1) y=4x + 2

thankyou!

Answer 1

The domain is the set of acceptable values of x.

Is there any value of x that you think should be excluded from the domain of y = 4x+2?

Answer 2

Sorry, I don't understand that but how do I put it into interval notation?

Answer 3

I hear you but if you don't understand what the domain of a function is, then it will be, in my opinion, impossible to understand the meaning of the interval notation.

Answer 4

If you know the domain and range and just want to know how to write it in interval notation, then we can do that.

Answer 5

I understand that the domain is the set of x- values, and I understand interval notation, I just don't know how to do that specific equation

Answer 6

If you seek the answer, I believe it shall be\[(-\infty,\infty)\]

Answer 7

isn't that the set of reals?

Answer 8

Same.

Answer 9

Or, you could use \[\forall x\in R\]

Answer 10

thanks :)

Answer 11

No probs
