JEE MainMathematicsDefinite IntegrationMCQ+4 / −1
Let the function f:[0,2]→Rf:[0,2] \rightarrow \mathbb{R}f:[0,2]→R be defined as f(x)={emin⁡{x2,x−[x]},x∈[0,1)e[x−log⁡ex],x∈[1,2]f(x)= \begin{cases}e^{\min \left\{x^{2}, x-[x]\right\},} & x \in[0,1) \\ e^{\left[x-\log _{e} x\right]}, & x \in[1,2]\end{cases}f(x)={emin{x2,x−[x]},e[x−loge​x],​x∈[0,1)x∈[1,2]​ where [t][t][t] denotes the greatest integer less than or equal to ttt. Then the value of the integral ∫02xf(x)dx\int_{0}^{2} x f(x) d x∫02​xf(x)dx is :
