How do you do the limit problems?
I originally thought the limits were like the horizontal asymptotes but now I'm not so sure..

lim as x approaches 4 of [sqrt(x)-2] / [x-4] = ____________


and..


If f(x) = sqrt[2-5x] , where x, f(x) is an element of the Reals then the range of f(x) is {f(x)| f(x) greater than or equal to ______________}

Is this as simple as I think it is? Isn't it always 0?
