1.	If f(x)=⎧⎪⎪⎨⎪⎪⎩3x−x22x<2[x−1],2≤x<3x2−8x+17,x≥3 then which of the following hold(s) good? [Note ; [x] denotes largest integer less than or equal to x,]
Answer» $I f f (x) = ⎧ ⎪⎪ ⎨ ⎪⎪ ⎩ \begin{matrix} \frac{3 x - x^{2}}{2} & x < 2 [x - 1], & 2 \leq x < 3 x^{2} - 8 x + 17, & x \geq 3 \end{matrix}$ then which of the following hold(s) good? [Note ; [x] denotes largest integer less than or equal to x,]
