Choose one function. Sketch the graph and identify the VERTEZ, DOMAIN, RANGE, and the OPENING of the GRAPH. Is the vertex is at minimum or maximum. What is the equation of axis of symmetry? *

Answer:
The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .
