The domain of the function is the set of all real numbers that make the function well-defined or workable. In this case, the function is a square root, so the domain of the function is all real numbers that make the expression inside the square root non-negative.
The expression inside the square root is 3x+3. To find the domain, we need to solve the inequality:
3x + 3 ≥ 0
Subtracting 3 from both sides gives:
3x ≥ -3
Dividing by 3 gives:
x ≥ -1
Therefore, the domain of the function y = √(3x + 3) is all real numbers greater than or equal to -1.
What is domain of the function?
y= root of 3x+3

what are the signs for the equation
For the equation y = √(3x + 3), the sign of the square root function (√) is always non-negative in its domain (the values of x for which the function is defined).
Since we found that the domain of the function is all real numbers greater than or equal to -1, the square root function will always output non-negative values in that domain. This means that the result of the function will always be positive or zero in the given domain.
Therefore, the sign of the function y = √(3x + 3) is non-negative in the domain x ≥ -1.
