Question

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

Answer 1

The equation given to us is in the Standard form
`y = ax^2 + bx + c` where `a = -2, b = -5 and c = 7`

The Axis of Symmetry is given by the formula `x = -(-5)/(2*(-2))`

`x = 5/4`

`color (green)( x = 5/4` is the Axis of Symmetry of the Parabola with the equation `y=-2x^2-5x+7`
