Question

 If p(x) = x2 + 3x – 2, then find the value of p(2) – p(–2) + p 1/2

Answer 1

Answer:

47/4

Step-by-step explanation:

$p(2) = {2}^{2} + 3(2) - 2 \\ 4 + 6 - 2 \\ 8 \\ p( - 2) = { - 2}^{2} + 3( - 2) - 2 \\ 4 - 6 - 2 \\ - 4 \\ \\ p( \frac{1}{2} ) = { \frac{1}{2} }^{2} + 3( \frac{1}{2} ) - 2 \\ \frac{1}{4} + \frac{3}{2} - 2 \\ \frac{1 + 6 - 8 }{4} \\ - \ \frac{1}{4} \\ 8 + 4 - \frac{1}{4 } \\ \frac{32 + 16 - 1 }{4} \\ \frac{47}{4}$
