What is wrong with \(\mathop \smallint \limits_{ - 1}^3 \frac{1}{{{x^2}}}dx = - \frac{4}{3}?\)
1
\( - \frac{4}{3}\left( {negative} \right)\)
2
f(x) is continuous at the endpoints
3
The fundamental theorem of calculus can be applied
4
Discontinuity at x = 0 and hence \(\mathop \smallint \limits_{ - 1}^3 \frac{1}{{{x^2}}}dx\) does not exist.
