Answer:
[tex]x=-\dfrac{1}{6}[/tex]
Step-by-step explanation:
For a quadratic function in standard form [tex]y=ax^2 + bx + c[/tex], the axis of symmetry can be expressed as [tex]x=\dfrac{-b}{2a}[/tex]
For the equation [tex]y=3x^2+x[/tex]
[tex]a=3, b=1, c=0[/tex]
Therefore, the axis of symmetry is [tex]x=-\dfrac{1}{6}[/tex]
