Write the domain in interval notation. (a) a (x)=√x+16 (b) b (x)=√16-x 1 (c) c (x) = x+16 Part 1 of 3 (a) a (x)=√√√x+16 The domain in interval notation is

Rationalize the numerator: [√(x + 3) - √x] / 3

I have to find the domain of f(x)= (sqrt: x + 8)/ x-8 and I understand how to find the domain of a fraction but I'm not able to figure out how the sqrt plays into the outcome of the domain in Interval notation

d. x(1+x²)
