I'm having trouble with a couple of questions. I'm not sure about the last two, but I know that I need to use the limit to the lower bound for the first problem.
1) Integral of (3)/(x^2) dx bounded by -1 (lower) to 1 (upper)
2) Integral of (x^(-5/4)) dx bounded by 1 (lower) to infiniti (upper)
3) Integral of (1)/((8-x)^1/3) dx bounded by 0 (lower) to 8 (upper)
Thanks in advance for the help.
