Linear equations and functions | 8th grade math | Khan Academy
When distances, prices, or any other quantity in our world changes at a constant rate, we can use linear functions to model them. Let's learn how different representations, including graphs and …
Standards Mapping - Common Core Math | Khan Academy
Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) …
Basic derivative rules: find the error (video) | Khan Academy
We analyze two students' attempts to differentiate linear functions using basic rules. One student forgets a negative sign, while another incorrectly assumes the derivative of a product equals …
Understanding the trapezoidal rule (article) | Khan Academy
For the trapezoid rule, you take the average y-value. For the midpoint rule, you take the average x-value. Unless the curve happens to go right through the center of that rectangle (such as a …
Understanding linear relationships | Lesson - Khan Academy
Linear functions are usually written in either slope-intercept form or standard form. We need a thorough and flexible understanding of these forms in order to approach many SAT questions …
Transformations of functions | Algebra 2 | Math | Khan Academy
Importantly, we can extend this idea to include transformations of any function whatsoever! This fascinating concept allows us to graph many other types of functions, like square/cube root, …
Clarifying standard form rules (video) | Khan Academy
Writing linear equations in standard form becomes more useful when dealing with more than two variables, especially when solving systems of linear equations.
