Unformatted text preview: k is its ycoordinate. Questions: 1. When does a parabola open up? When does it open down? f ( x ) = ax 2 + bx + c f ( x ) = a ( xh ) 2 + k 2. How do we nd the coordinates of the vertex of a parabola? f ( x ) = ax 2 + bx + c f ( x ) = a ( xh ) 2 + k 3. How do we nd the equation of axis of symmetry? Examples: 1. Find the quadratic function that has vertex (2,3) and whose graph passes through the point (0,2). 2. Sketch the graph of f ( x ) = 25x 2 identifying the vertex and intercepts if there are any. 3. Sketch the graph of f ( x ) = x 2 + 3 x + 1 / 4 identifying the vertex and intercepts if there are any....
