Question

What is the domain of the function?

y = √4x - 4

A. x > -1
B. x ≥ 1
C. x ≥ -1
D. x ≥ 1

Answer 1

the value of x is called domain

Answer 2

Yes, the domain are your x values.

Answer 3

option B nd option D are same?!

Answer 4

Yeah, just an accidental repeat by my teacher or something. Sorry about that

Answer 5

i think ur equation is
y=√(4x-4)?

Answer 6

its ok. no problem. just say something to follow us

Answer 7

if 4x-4<0
then wt will b the value of y

Answer 8

The restriction on the values of x which we can enter into this function and get a value out for y lies in the square root:
\[\sqrt{4x-4}\]

Here we cannot get the square root of a negative number, so

4x - 4 >= 0

This only occurs if x is >= 1 (B.).
