This math topic involves practicing the skill of identifying graphs of quadratic functions based on given ranges. Each question presents a range using interval notation and asks to choose the correct graph which corresponds to a quadratic function with that specific range. The ranges given vary from ones that start at a particular value and extend to infinity to ranges that extend from negative infinity to a specified endpoint. This exercises the student's ability to understand and visualize how changes in a function's equation affect its graphical representation and its range.
