f(x) = sqrt(5 - (sqrtx))

my solution:

5 - (sqrt x) >=0

-(sqrt x) >= -5

(sqrt x) <= 5

x <= 25

(-infinity, 25]

is this correct?

- is this correct?- math -
**Steve**, Sunday, February 12, 2012 at 5:47pmno, since when x < 0, sqrt(x) is not defined. so, neither is sqrt(5-sqrt(x))

the domain is just [0,25]
