Question

expresión algebraica de f(x)= -0,5(x+3)(x+1)(x-8)

Answer 1

Explicación paso a paso:

$f(x) = - 0.5(x + 3)(x + 1)(x - 8) \\ f(x) = - 0.5( {x}^{2} + x + 3x + 3)(x - 8) \\ f(x) = - 0.5( {x}^{2} + 4x + 3)(x - 8) \\ f(x) = - 0.5( {x}^{3} - 8 {x}^{2} + 4 {x}^{2} - 32x + 3x - 24) \\ f(x) = - 0.5( {x}^{3} - 4 {x}^{2} - 29x - 24) \\ f(x) = - 0.5 {x}^{3} + 2 {x}^{2} + 14.5x + 12$
