Khan Academy: Interpreting Linear Functions Harder Example

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

Watch [2:16] Sal work through a basic Interpreting linear functions problem.

Watch [3:26] Sal work through a harder Graphing linear equations problem.

The final segment in the Khan Academy's series on function inverses. Similar to the previous video, this segment does another example for finding the inverse of a quadratic function. Again the instructor explains the need for restraints...

In this video lesson [2:16] watch Sal work through a basic Interpreting linear functions problem.

Practice writing a linear function that represents a real-world relationship that is given verbally. Functions are written using function notation.

This video goes through two examples of how to find the inverse of a linear function. Both the function and its inverse are graphed on the same coordinate axis where it is shown that they are a reflection of each other over the line y=x....

Given a function find out which graphs shows functions increasing faster than the given one.

The video from Khan Academy provides practice questions for the SAT. Students will watch Sal work through a harder right triangle trigonometry problem.

This video lesson from Khan Academy covers congruence and similarity for eighth grade mathematics students. Watch Sal work through a harder congruence and similarity problem.
