# What is the axis of symmetry of the graph of  y=-2x^2-5x+7?

$y = a {x}^{2} + b x + c$ where $a = - 2 , b = - 5 \mathmr{and} c = 7$
The Axis of Symmetry is given by the formula $x = - \frac{- 5}{2 \cdot \left(- 2\right)}$
$x = \frac{5}{4}$
color (green)( x = 5/4 is the Axis of Symmetry of the Parabola with the equation $y = - 2 {x}^{2} - 5 x + 7$
