EXERCISE 2.2
Arna
1. Find the value of the polynomial 5x - 4x2 + 3 at
Go x=0
(ii) x=-1
(iii) x=2
2. Find p(0), p(1) and p(2) for each of the following polynomials:
(i) p(y) = y - y + 1 (ii) p(t) = 2 + + + 2t - A
(iii) p(x)= x
(iv) p(x) = (x - 1) (x + 1)​

Answer 1

Answer:

1.(i)x = 0

Explanation:

5x – 4x2 + 3

Plug x = 0 we get

=>5(0) – 4(0)2 + 3

=>0 -0 + 3

=> 3

2. (ii) x = –1

Plug x = - 1 we get

=>5x – 4x2 + 3

=>5(-1) – 4(-1)2 + 3

=> -5 – 4 +3
