A parabola has zeros at (5,0) and (-3,0) and passes through point (6,18) determine the axis of symmetry

worty [1.4K]

Answer:

The axis of symmetry is $x=1$

Step-by-step explanation:

we know that

In a vertical parabola, the axis of symmetry is equal to the x-coordinate of the vertex

In this problem we have a vertical parabola open upward

The x-coordinate of the vertex is equal to the midpoint between the zeros of the parabola

$x=\frac{5-3}{2}=1$

therefore

The axis of symmetry is $x=1$
