Answer:
axis of symmtery: x = 3 or h = 3
Step-by-step explanation:
The vertex (h, k) of a parabola is the point wherein the graph intersects the axis of symmetry—the imaginary straight line that bisects a parabola into two symmetrical parts, where x = h.
- In the standard form of quadratic equation, y = ax² + bx + c, the equation of the axis of symmetry is: [tex]x = \frac{-b}{2a}[/tex].
- In the vertex form of the quadratic equation, y = a(x - h)² + k, the equation of the axis of symmetry is: [tex]h = \frac{-b}{2a}[/tex].
Regardless of whether the quadratic equation is in standard or vertex form, the x-coordinate (h) of the vertex determines the axis of symmtetry, hence, x = h.
Therefore, given that the vertex of a parabola is at point (3, 5), then it means that the axis of symmetry occurs at x = 3 or h = 3.
