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 $y=3x^2+5x-7$

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