This video gives you the fastest and easiest method to understand and sketch parabolas—no complex math required. We break it down step-by-step: finding the vertex, identifying the axis of symmetry, ...

Quadratic graph lines are U- or Ո-shaped, which is called a parabola. A linear graph can be drawn using only three points. A quadratic graph is a curve, so more points are plotted to support accuracy.

An equation of the form \(y = mx + c\) where \(m\) and \(c\) are numbers, gives a straight line when values of \(x\) and corresponding values of \(y\) are plotted on a grid. A straight line is a ...

Approaching negative infinity: The graph falls indefinitely as x approaches positive or negative infinity. Approaching a horizontal asymptote: The graph approaches a horizontal line as x approaches ...

As part of a series of electronic professional development experiences for educators, the NASA Explorer Schools project is hosting a 60-minute Web seminar on Sept. 27, 2011, at 8 p.m. EDT. Investigate ...

Look for Key Features: Identify critical points and characteristics such as intercepts, vertices, asymptotes, and symmetry. Test Points: Choose a few points on the graph and plug their coordinates ...
