ii) the volume of cork and

iii) the relative density of cork.​

Answer 1

Answer:

2. Which of the following functions has zeros 1 & 0?

M. P(x) = x2 - 2x + 1 A. P(x) = x2 + 2x + 1 T. P(x) = x2 + x

H. P(x) = x2 - X

3. Which of the following polynomial functions have -1, -2 and -3 as zeros?

M. P(x) = (x - 1) (x - 2) (x - 3)

T. P(x) = (x + 1) (x + 2)(x + 3)

A. P(x) = (x + 1)(x - 2) (x + 3)

H. P(x) = (x - 1) (x +2) (x – 3)
