Question

f(x)
${2x}^{2} + 2x - 6$
si f(-1/2)​

Answer 1

Respuesta:

$f(x) = {2x}^{2} + 2x - 6 \\ f( - \frac{1}{2} ) = 2 \times {( - \frac{1}{2} )}^{2} + 2 \times ( - \frac{1}{2} ) - 6 = 2 \times \frac{1}{4} + ( - 1) - 6 = \frac{1}{2} - 1 - 6 = \frac{1}{2} - \frac{2}{2} - \frac{12}{2} = - \frac{13}{2}$
