Quadratics Function

1. Quadratic Function

2. Learning objective Students are able to understand the properties of quadratic function Students are able to solve quadratic function problems.

3. Identify the quadratic graph by Equations Function Opens upward/downward Having minimum or maximum point/vertex Go to the right or to the left of y-axes The coordinate of y-intercept Function Opens upward/downward Having minimum or maximum point/vertex Go to the right or to the left of y-axes The coordinate of y-intercept

4. Identify the quadratic graph by Equations Function The coordinate of x-intercept/roots The coordinates of minimum or maximum points Symmetry lines The graph floating or intersecting x-axes Function The coordinate of x-intercept/roots The coordinates of minimum or maximum points Symmetry lines The graph floating or intersecting x-axes

5. Quadratic function problems Given quadratic function . The graph opens upward/downward The coordinate of the y-intercept The graph floating or intersecting x-axes If the graph intersects x-axes, find the coordinate of the x-intercept (roots) The graph of the function has minimum/maximum vertex The coordinate of the vertex The domain of the function The range of the function The symmetry line equation If the input x is 5, what is the output of the function? If the output equals to 4, what is the input x for the function?
