Answer:

Step-by-step explanation:

To evaluate f??(- 4) substitute x = - 4 into f(x), that is

f(- 4) = 2(- 4)² + 4(- 4) - 7 = (2 × 16) - 16 - 7 = 32 - 23 = 9 → C

Solve square root <br> X^2+12x+43=0

AlekseyPX

$x^2+12x+43=0
$

$x= \dfrac{-b+ \sqrt{b^2-4ac} }{2a}, \dfrac{-b- \sqrt{b^2-4ac} }{2a}$

$x= \dfrac{-12+ \sqrt{12^2-4*43} }{2}$ , $\dfrac{-12- \sqrt{12^2-4*43} }{2}$

$x= \dfrac{-12+2 \sqrt{7i} }{2}, \dfrac{-12-2 \sqrt{7i} }{2}$

$x=-6+ \sqrt{7i},-6- \sqrt{7i}$
