Find the functions a) f o g, b) g o f, c) f o f, d) g o g, and their domains. f(x)= square root of x, g(x)= cube root of 1-x These are my answers, but I am not sure about them and I only figured out one domain... that is the part that really confuses me.

I used an online math site, to explain quadratic equations. But the thing is, they said that (-4)^2 is 16, but my calculator said -16. Why is that? And also, how does the square root of 40 break down into the square root of 4 and the square root of ten?
