1.	Let ∫ex2⋅ex(2x2+x+1) dx=ex2f(x)+c, where c is constant of integration. If the minimum value of f(x) is m, then the value of [−1m] is (where [.] represents grestest integer function)
Answer» Let $\int e^{x^{2}} \cdot e^{x} (2 x^{2} + x + 1) d x = e^{x^{2}} f (x) + c$ , where $c$ is constant of integration. If the minimum value of $f (x)$ is $m$ , then the value of $[- \frac{1}{m}]$ is (where [.] represents grestest integer function)
