Question

What is the domain of the function y= the square root of x+6-7

Answer 1

domain of y = sqrt(x + 6) - 7 <br><br>
Finding domain is trying to check the following valid conditions <br>
<br>
condition 1: check for x such that the value in square root must greater or equal to 0 <br>(applicable here) <br>x + 6 >= 0<br>x > -6 ... this is the answer<br><br>
condition 2: check for x such that the divisor must not be zero <br>(not applicable here) <br><br>
condition 3(misc) : check some functions <br>for example ... log(0) is invalid...<br>

Answer 2

x>-6 is what i believe the answer is.
hope this helps!
