Learning Task 2. Sketch the graph of the following. Give the domain and range
of the following quadratic function defined by the given equation. Determine
the direction where the parabola opens, its vertex, its axis of symmetry, and its
x- and y- intercepts.
1. y = x2 + 8x + 4
3. y = -3x2 + 12x - 7
2. y = x2 +4x + 5
4. y = 2x2 - 4x - 6
