Answer 2

Answer:

$when \: \: x = 1\\ p(x) = 4 {x}^{2} + 2x - 7 \\ p(1) = 4 {(1)}^{2} + 2(1) - 7 \\ p(1) = (4 \times 1) + (2 \times 1) - 7 \\ p(1) = 4 + 2 - 7 \\ p(1) = \underline{ \underline{ \bf - 1}} \\ \\ when \: \: x = - 1 \\ p(x) = 4 {x}^{2} + 2x - 7 \\ p( - 1) = 4 {( - 1)}^{2} + 2( - 1) - 7 \\ p( - 1) = (4 \times 1) + ( - 2) - 7 \\ p( - 1) = 4 - 2 - 7 \\ p( - 1) = \underline{ \underline{ \bf - 5}}$
