Question

if p(x)=5x_4x²+3 then p(_1)​

Answer 1

Step-by-step explanation:

Here,

P(x) = 5x - 4x² + 3

p( -1) = 5× ( -1) - 4x( -1)² + 3

p( -1) = -5 - 4 +3

P( -1) = -7 + 3

P( -1) = -4 ANSWER

Answer 2

Answer:

$p(x) = 4 {x}^{2} + 5x + 3 \\ \\ = p(1) = 4 \times {1}^{2} + 5 \times 1 + 3 \\ \\ = 4 + 5 + 3 = 12$
