Question

Urgent ! i need to know this

Answer 1

x = 4

Explanation:

The axis of symmetry is a vertical line that divides the parabola (this U-shaped curve) into 2 exact halves.

Even as the y value changes, the equation of the line will always have an x of 4.

Answer 2

x = 4

Explanation:

the axis of symmetry is a vertical line passing through the vertex of the parabola with equation

x = c ( c is the value of the x- coordinate of the vertex )

the vertex has coordinates (4, - 9 ) with x- coordinate 4 , then

x = 4 ← equation of axis of symmetry
