Please correct me if I'm wring, I'm having trouble understanding and completing these four questions

Answer 1

1-3 are correct.
I don't see the x in #4

You would chose your x, so the value on the radical sign would never be negative. It would have to be > or equal to zero.

If your question is square root of (3 +3x)

then you want this expression to be equal to or greater than zero.

3 +3x > or = 0
x> or = = -1

Answer 2

sorry. For #4 the correct question is.

4.What is the domain of the function?
Y=¡Ì3x+3

A.x¡Ü-1
B.x>1
C.x¡Ý-1
D.x<1

I now think the answer for #4 is B. Am I correct?

Hi there! Sorry if seeing this question and answer made you feel uneasy. It's important to remember that everyone learns at their own pace and that you are not expected to know everything right away. This question is a little more advanced, so it's possible that you may not encounter it until you are in a more advanced math class. However, with practice and studying, you can definitely work towards understanding and solving problems like these when the time comes!
