Exponential graphs | Lesson (article) | Khan Academy
What are exponential graphs? In an exponential function, the output of the function is based on an expression in which the input is in the exponent. For example, f (x) = 2 x + 1 is an exponential …
Recognizing functions from graph (video) | Khan Academy
If you can draw a vertical line anywhere on the graph and only pass thru one point on the graph at a time, then the graph is a function. The graph in the video fails the vertical line test because …
Linear equations, functions, & graphs | Khan Academy
This topic covers: - Intercepts of linear equations/functions - Slope of linear equations/functions - Slope-intercept, point-slope, & standard forms - Graphing linear equations/functions - Writing …
What is a function? (video) | Functions | Khan Academy
If we have a function with 2 inputs to create 1 output, we can graph in a 3 dimensional graph of (x, y, z). Once you go to even higher inputs, we typically would not graph them as we don't what a …
Even and odd functions: Graphs (video) | Khan Academy
They are two different types of functions. Even functions have symmetry across the y-axis. Odd functions have symmetry across the origin. Can you have a function that is both even and odd …
Rational functions (video) - Khan Academy
We break down the definition of the function given in set-builder form and plot the graph by connecting points on the cartesian plane. Domain and Range is calculated through visually …
Connecting f, f', and f'' graphically (video) | Khan Academy
The way I'm going to tackle it is I'm gonna try to sketch what we can about the derivatives of each of these graphs, or the functions represented by these graphs.
