Question

The graph of the function f(x)=-2x^2+6x-3 opens and has a value

Answer 1

2x^2 +6x -3. if we are using the quadratic equation this would be

$- 6$

+ or -

$\sqrt{{6}^{2} - 4 \times 2 \times ( - 3) }$

all over 2×2

this simplifies to

$x = - \frac{3}{2} + \frac{ \sqrt{15} }{2}$

and

$x = - \frac{3}{2} - \frac{ \sqrt{15} }{2}$
