Question 853683

What is the equation of the axis of symmetry of the graph y=4x^2-5x+16
<pre>
Axis of symmetry or x-coordinate of vertex = {{{- b/2a}}}

With a being {{{4}}}, and b being: {{{- 5}}}, axis of symmetry or x-coordinate of vertex is:
{{{- (- 5/2(4))}}}, or {{{- (- 5/8)}}}, or {{{highlight_green(5/8)}}}
You can do the check!! 

If you need a complete and detailed solution, let me know!!
