Question

p(x)= 3x²+6x+1 p(-1)=? p(5)=?​

Answer 1

p(x) = 3x² + 6x + 1

p(-1) = 3(-1)² + 6(-1) + 1

p(-1) = 3 - 6 + 1

p(-1) = -2

p(5) = 3(5)² + 6(5) + 1

p(5) = 3(25) + 30 + 1

p(5) = 75 + 30 + 1

p(5) = 106

Answer 2

Answer:

answer: p(-1) = -2

p(5) = 106

Step-by-step explanation:

p(x) = 3x² + 6x + 1

then,

p(-1) = 3×(-1)² + 6×(-1) + 1

= 3×1 -6 +1

= 3-6+1

= 4-6

= -2

and

p(5) = 3×(5)² + 6×5 +1

= 3× 25 + 30 +1

= 75 + 30+1

= 106
