Question

What is the range og the function f(x)=-2 sqrt(x-3)-4?

Answer 1

I believe it is f(x)<=-4

Answer 2

this is\[ f(x)=-2 \sqrt{(x-3)}-4\]?

Answer 3

my bad umm i was thinking domain

Answer 4

Yep thats right @RaphaelFilgueiras =) Its all good @Outkast3r09

Answer 5

if the first part = 0 you get -4

Answer 6

however as x goes to infinity for the sq rt it goest to infiniyt also

Answer 7

mutliply -2 (infty) you simply get -infty so it's -infty,-4

Answer 8

Therfore it should be all real numbers? @Outkast3r09

Answer 9

no because the root cannot be negative so you'll never get a positive number

Answer 10

f(x)<=-4,since sqrt>=0
