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

There is no minus sign. -2 * -2 = 4

Domain: Do any of the criteria at the top of my post apply

Range: We need to know the sign of the constantm

What doesSimilar 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

.............x=-2

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?X3Rmean? Your answer is not right since 2isin the domain (as is -2 in case that was a typo)

For the domain solve

For the range what do you know about the graph of a square root?
