Answer 2

Answer:

$\frac{1}{8}$

Step-by-step explanation:

substituting the value of 'x' in the following question...  

= $(\frac{-1}{2})^{3} + 3 (\frac{-1}{2}) ^{2} + 3(\frac{-1}{2}) + 1$

$=\frac{-1}{8} + \frac{3}{4} - \frac{3}{2} + 1\\\\=\frac{-1}{8} + \frac{6-12}{4 * 2} + 1\\\\= \frac{-1}{8} + (\frac{-6}{8}) + 1\\\\= \frac{-1}{8} - \frac{6}{8} + 1\\\\= \frac{-7}{8} + 1\\\\= \frac{-7+8}{8} \\\\= \frac{1}{8}$
