Question

EXERCISC 2B
1 If p(x) = 5 - 4x + 2x?, find
(i) p(0), p(3) p(-2)​

Answer 1

1. p(x)=5-4x+2x=5-2x

• p(0)=5
• p(3)=-1
• p(-2)=9

Answer 2

Answer:

p(0) = 5

p(3) = 11

p(-2) = 21

Step-by-step explanation:

p(0) = 5 - 4*0 + 2*0*0

p(0) = 5

p(3) = 5 - 4*3 + 2*3²

p(3) = 5 - 12 + 18

p(3) = 11

p(-2) = 5 - 4*(-2) + 2*(-2)²

p(-2) = 5 + 8 + 8

p(-2) = 21
