Answer: The axis of symmetry is x=1.
Explanation:
The given function is,

The degree of the equation is 2. SInce it is a quadratic function therefore the graph of the function is a parabola.
The axis of symmetry of a parabolic function
is a vertical line,

Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,



Therefore, the axis of symmetry is x=1.
My friend says 5 is 60 and 6 is b.
