Answer 2

for domain you would take the function under the square root symbol and set it greater than or equal to zero , resulting in x is greater than or equal to -1 for domain.

Answer 3

The reason is because for x < -1 you'd be taking the square-root of a negative number which is imaginary and won't show up on the graph.

Answer 4

Range would be -infinity to positive infinity I believe.

Answer 5

f(x) can never be positive, so range can't go to positive infinity.

Answer 6

geoffb is correct. A negative square-root is always negative, so it maxes out at y=0.
