Question

can someone help find the domain please?
f(x)=-sqrt(x+1)

Answer 1

the stuff inside radical must be >= 0 if the f(x) is a real valued function

Answer 2

so for domain you may simply solve :

x+1 >=0

Answer 3

x>-1?

Answer 4

include equal sign also

Answer 5

x >= -1

Answer 6

is that the answer or is there more steps?

Answer 7

thats the answer
x must be >= -1

Answer 8

its greater than and equal to -1?

Answer 9

i got it! thanks!

Answer 10

would the range be less than or equal to 0?

Answer 11

thats right ! range will be <= 0
because sqrt is always >=0 and so taking negative of it gives you <= 0

Answer 12

okay thanks :)
