Find the value of 5x-4xsquare+3 at (1)x=0 (2)x=-1 (3)x=-2

Answer 1

Question:-

p(x) = 5x - 4x² + 3

Find

1. p(0)
2. p(-1)
3. p(-2)

Answer:-

p(x) = 5x - 4x² + 3

=> p(x) = - 4x² + 5x + 3

Finding p(0)

p(0) = (- 4 * 0 * 0) + (5 * 0) + 3

=> p(0) = 0 + 0 + 3

=> p(0) = 3

Finding p(-1)

p(-1) = (-4 * -1 * -1) + (5 * -1) + 3

=> p(-1) = -4 - 5 + 3

=> p(-1) = -6

Finding p(-2)

p(-2) = (-4 * -2 * -2) + (5 * -2) + 3

=> p(-2) = -16 - 10 + 3

=> p(-2) = -23
