The value of the integral $\int\limits_0^1 e^{x^2} d x$ lies in the interval
Answer & explanation
Correct answer: option 3
Since $e^{x^2}$ is an increasing function on $(0,1)$.
∴ $m=e^0=1$ and $M=e^1=e$, where
$m$ and $M$ are minimum and maximum values of $f(x)=e^{x^2}$ in the interval $(0,1)$ for all $x \in(0,1)$
$\Rightarrow 1(1-0)<\int\limits_0^1 e^{x^2} d x<e(1-0) \Rightarrow 1<\int\limits_0^1 e^{x^2} d x<e$
