Concept explainers
Graph the function. Label the vertex and axis of symmetry and x-intercepts.
Axis of symmetry (x)
Vertex
X-intercept =
Given:
The given function
Concept Used:
- The vertex is the highest point if the parabola opens downward and the lowest point if the parabola opens upward.
- The axis of symmetry is the line that cuts the parabola into 2 matching halves and the vertex lies on the axis of symmetry.
- The x-intercept is the point where a line crosses the x-axis.
Calculation:
