Khan Academy: Algebra: Graphing a Basic Function

This video demonstrates how to graph a linear equation by creating a table of x, y values to use as coordinates for the graph of the line. The second example demonstrates how to take a word problem and create a table of values to graph...

Video graphing a quadratic function by evaluating it for seven different values and plotting the resulting points. [4:04]

Video shows an example of finding the horizontal and vertical asymptotes of a rational function. Also shows finding the behavior of the function as it approaches the asymptotes and uses this information to sketch a graph of the function....

Given the graph of a step function, find the function's outputs for given specific inputs. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Video showing how to graph a radical function by specifically choosing values for x that result in easy-to-plot values of y and then plotting the points. [10:17]

Video showing how to graph an exponential function by evaluating the function for chosen values of x and plotting the resulting points. [5:32]

Video graphing a parabola by plotting the roots, vertex and axis of symmetry. Roots of the quadratic function are found by factoring. Vertex of the parabola is found by three different methods: taking the midpoint of the roots, finding...

Practice evaluating the inverse function of a function that is given either as a formula, or as a graph, or as a table of values. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or...

Given the formula of a piecewise function, evaluate it for a specific input. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice finding the formula of the inverse function of a given polynomial, radical, or rational function. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
