Answer:

P (-2)= 3(-2)*2 + (-2) + 7

= 3 x 4 - 2 + 7

12 - 2 +7

= 17

Hope it's helpful to you.

According to my point of view this is the correct answer.

Answer:

p(x) =  {3x}^{2}  + x + 7 \\ p(x) = 3 \times  { (- 2)}^{2}  + ( - 2) + 7 \\  \\  = 3 \times 4 - 2 + 7 \\ \\ =  12 + 5 \\  = 17

Hence, 17 is the value of p(x).
