(1,5) is on the graph of the function y=3x+2
we know that
The equation in vertex form of a vertical parabola is of the form
where
is the vertex of the parabola
and
is the axis of symmetry
if
-----> open upward
if
-----> open downward
In this problem we have


This is a vertical parabola open upward
The vertex is a minimum
therefore
<u>the answer is</u>
the vertex is the point 
the axis of symmetry is 
see the attached figure to better understand the problem
