$\frac{-4+4}{\sqrt{3\cdot -4+13}-1}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(-4)lim((x+4)/((3x+13)^1/2-1)). Evaluate the limit \lim_{x\to-4}\left(\frac{x+4}{\sqrt{3x+13}-1}\right) by replacing all occurrences of x by -4. Subtract the values 4 and -4. Multiply 3 times -4. Subtract the values 13 and -12.
