Question:

Plot the vertex, the y-intercept, and the reflection of the y-intercept in the axis of symmetry of the graph of f(x) = -3x² + 12

Plot the vertex, the y-intercept, and the reflection of the y-intercept in the axis of symmetry of the graph of f(x) = -3x² + 12x - 4. Then describe the range of the function.
