Ex 2.2, 1 (i) Find the value of the linear polynomial 5x – 3 if: (i) x = 0 Let p(x) = 5x – 3 For value of polynomial at x = 0, we put x = 0 in p(x) Putting x = 0 in p(x) p(0) = 5 × 0 – 3 = 0 – 3 = –3 Ex 2.2, 1 (ii) Find the value of the linear polynomial 5x – 3 if: (ii) x = –1 Since p(x) = 5x – 3 Putting x = –1 in p(x) p(–1) = 5 × (–1) – 3 = –5 – 3 = – ( 5+ 3) = –8 Ex 2.2, 1 (iii) Find the value of the linear polynomial 5x – 3 if: (iii) x = 2 Since p(x) = 5x – 3 Putting x = 2 in p(x) p(2) = 5 × 2 – 3 = 10 – 3 = 7
