First look at the function \[f(x) = \sqrt{x}\]Its graph looks like this|dw:1378512376997:dw| Notice that the square root of a number is never negative. The range is basically the possible y-values for that function. The range for sqrt(x) is [0,infinity) and the -1 causes the graph to shift down 1, changing the range to [-1, infinity)

ok so the final answer is -1,infinity?

i understand the graph i just thought for some reason it couldnt be negative:(

\[[-1,\infty)\] The [ means "inclusive" with regard to the -1. You're right that sqrt(x) can't be negative, but sqrt(x)-1 can be. Just plug in 0 for x:\[\sqrt{0}-1 = -1 \]which is negative
