How do you find the vertex and axis of symmetry, and then graph the parabola given by: #y= -3x^2 + 5#?
1 Answer
Axis of symmetry is
Vertex is
The graph will be a downward opening parabola.
Explanation:
Axis of Symmetry
The axis of symmetry is determined using the formula
The axis of symmetry is
Vertex
The vertex is the maximum or minimum point on the parabola. In this case, since the coefficient of
The
To find the value of
The vertex is
Determine several points on both sides of the axis of symmetry.
Plot the points on a graph and sketch a curved parabola through the points. Do not connect the dots.
