r²Quadratic polynomial.
7x³ Cubic polynomial.
Let p(x) = 5x - 4x² + 3 (i) Putting x = 0, we get p(0) = 5 × 0 - 4(0)² + 3 = 3
Let p(x) = 5x – 4x² + 3 (i) Putting x = 0, we get p(0) = 5 × 0 – 4(0)² + 3 = 3
Let p(x) = 5x – 4x² + 3 (ii) Putting x =-1, we get P(-1) = 5 × (-1) - 4(-1)² +3 = -5- 4 + 3 = -6
Let p(x) = 5x – 4x² + 3 (ii) Putting x =-1, we get P(-1) = 5 × (-1) – 4(-1)² +3 = -5- 4 + 3 = -6
Let p(x) = 5x – 4x² + 3 (iii) Putting x = 2, we get p(2) = 5 × 2- 4(2)² + 3 = 10 - 16 + 3 = -3
Let p(x) = 5x – 4x² + 3 (iii) Putting x = 2, we get p(2) = 5 × 2- 4(2)² + 3 = 10 – 16 + 3 = -3
