Question

What is the axis of symmetry of the graph of `y=3x^2+5x-7`?

Answer 1

The equation given to us is in the Standard form
`y = ax^2 + bx + c` where `a = 3, b = 5 and c = -7`

The Axis of Symmetry is given by the formula `x = -b/(2a) = -(5)/(2*(3))`

`x = -5/6`

`color (green)( x = -5/6` is the Axis of Symmetry of the Parabola with the equation `y=3x^2+5x-7`
