·
Identify the domain and range for a relation, given a set of ordered pairs, a table, or a graph.
For each x in the domain of f, find f(x).
Identify the zeros of the function algebraically and confirm them, using the graphing calculator.
Identify the domain, range, zeros, and intercepts of a function presented algebraically or
graphically.
Recognize restricted/discontinuous domains and ranges.
Recognize graphs of parent functions for quadratic functions (y=x2).
Identify x-intercepts (zeros), y-intercepts, symmetry, intervals for which the function is increasing
or decreasing, points of discontinuity, and maximum and minimum points, given a graph of a
function.
Describe continuity of a function on its domain or at a point.
Express intervals using correct interval notation and/or a compound inequality.
Write an equation of a line when given the graph of a line.
Write the equation of a quadratic function in (h, k) form given the graph of the parent function and
transformation information. (y = a(x-h)2 + k)
Describe the transformation from the parent function given the equation written in (h, k) form or
the graph of the function.
Given the equation of a function, recognize the parent function and transformation to graph the
given function.
Recognize the vertex of a parabola given a quadratic equation in (h, k) form or graphed.
Describe the parent function represented by a scatter plot.

Notes
Start with an introductory activity to hook the students, teach the content, follow up with additional
activities.
All activities can be done with a TI-83 or 84 and CBL.
Get Hiker and Ball Drop programs for the TI-84 plus to make data collection easier.
For better results use the bleachers and not a stairwell to collect data from falling objects.
