Question

If p(t) = t³ – 1, find the values of p(1), p(–1), p(0), p(2), p(–2).

Answer 1

This was very simple question.

Answer 2

Solution :

Given p(t) = t³ - 1

i ) p(1) = 1³ - 1 = 1 - 1 = 0

ii ) p(-1) = ( -1 )³ - 1 = -1 - 1 = -2

iii ) p(0) = 0³ - 1 = -1

iv) p(2) = 2³ - 1 = 8 - 1 = 7

v ) p(-2) = ( -2 )³ - 1 = -8 - 1 = - 9
