<PRE><B>Question 168335</B>
How would you write the equation for the axis of symmetry and find the coordinates of the vertex for the following quadratic function?&lt;/b&gt;


{{{y=7x^2+6x-5}}}
------------------------------
You have a quadratic with a=7, b=6, and c=-5.
Axis of symmetry is x = -b/2a
x = -6/(2*7) = -3/7
