Question

the vertex of the parabola is (3,4)
the axis of symmetry is
the parabola opens upwards

Explanation:

Step1: Recall axis - of - symmetry formula

For a parabola with vertex $(h,k)$, the equation of the axis of symmetry is $x = h$.

Step2: Identify h value from vertex

The vertex is $(3,4)$, so $h = 3$.

Answer:

$x=3$
