Answer:
a =15, b=2
Axis of Symmetry = [tex]\frac{-b}{2a}[/tex]
[tex]=\frac{-2}{2 * 15}[/tex]
= [tex]-\frac{1}{15}[/tex]
To find the y-value for the vertex sub in the axis of symmetry for x
[tex]y=15(-\frac{1}{15} )^{2}+2(-\frac{1}{15} )-8\\\\=-\frac{121}{15}[/tex]
∴ Vertex [tex](-\frac{1}{15}, -\frac{121}{15} )[/tex]
