Question

Evaluate x4 + 4x3 - 2x2 + 11x - 6 for x = 3

Answer 1

Step-by-step explanation:

$f(x) = {x}^{4} + 4 {x}^{3} - 2 {x}^{2} + 11x - 6$

$f(3) = {3}^{4} + 4. {3}^{3} - 2. {3}^{2} + 11.3 - 6$

$f(3) = 81 + 4.27 - 2.9 + 33 - 6$

$f(3) = 81 + 108 - 18 + 33 - 6$

$f(3) = 198$

Answer 2

Answer:

198

Step-by-step explanation:

x4 + 4x3 - 2x2 + 11x - 6 for x = 3

3^4 + 4 * 3^3 - 2 * 3^2 + 11 * 3 - 6 =

81 + 4 * 27 - 2 * 9 + 11 * 3 - 6 =

81 + 108 - 18 + 33 - 6 =

198
