Hope it helps you, sorry for cutting that line.

Answer 2

$4 {x}^{3} - 3 {x}^{2} + 5x + 7 \\ 4( { \frac{1}{2}) }^{3} - 3( { \frac{1}{2} ) }^{2} + 5( \frac{1}{2} ) + 7 \\ 4 \times \frac{1}{8} - 3 \times \frac{1}{4} + \frac{5}{2} + 7 \\ \frac{1}{4} - \frac{3}{4} + \frac{5}{2} + 7 \\ \frac{1 - 3}{4} + \frac{5 + 14}{2} \\ \frac{ - 2}{4 } + \frac{19}{2} \\ \frac{ - 1}{2} + \frac{19}{2} \\ \frac{ - 1 + 19}{2} \\ \frac{18}{2} \\ 9$

Hope my answer will help you..
