In general we start with the largest domain and exclude values from it. The largest domain is usually all the real numbers.
We can exclude values which make the denominator 0, make the argument of a logarithm 0 or negative or make a square root negative
Domain: Do any of the criteria at the top of my post apply
Range: We need to know the sign of the constant m
What does X3R mean? Your answer is not right since 2 is in the domain (as is -2 in case that was a typo)Similar Question: What is the domain and range of: m(x): (the square root of) x+2
m(x): (the square root of) x+2
Domain: x+2 = 0
Domain = X3R but can cannot be 2
I'm not sure if the last two lines are right? Can someone check them for me please?
For the domain solve
For the range what do you know about the graph of a square root?
