1.Let f:[−1,2]→Rf : [-1,2] \to \mathbb{R}f:[−1,2]→R be given by f(x)=2x2+x+[x2]−[x]f(x) = 2x^2 + x + [x^2] - [x]f(x)=2x2+x+[x2]−[x], where [t][t][t] denotes the greatest integer less than or equal to ttt. The number of points where fff is not continuous, is:Login to continueOnly logged in users canattempt or see the solution.
