Finding the domain and the range of a function that is given graphically.
How to find the domain of a function (video) | Khan Academy
Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real …
Domain and range of quadratic functions (video) | Khan Academy
Determine the domain and range of the function f of x is equal to 3x squared plus 6x minus 2. So, the domain of the function is: what is a set of all of the valid inputs, or all of the valid x values for this …
Domain and range from graph (practice) | Khan Academy
Given the graph of a function, determine its domain or range.
Functions | Algebra (all content) | Math | Khan Academy
This topic covers: - Evaluating functions - Domain & range of functions - Graphical features of functions - Average rate of change of functions - Function combination and composition - Function …
Finding domain and range using graph (video) | Khan Academy
Even if that function is not a polynomial. We break down the definition of the function given in set-builder form and plot the graph by connecting points on the cartesian plane. Since this function has a square …
Determine the domain of functions (practice) | Khan Academy
Determine the domain of a function according to the algebraic limitations of that function.
How to find the range of a function (video) | Khan Academy
The range of a function is the set of all possible outputs the function can produce. Some functions (like linear functions) can have a range of all real numbers, but lots of functions have a more limited set of …
Worked example: domain & range of piecewise linear functions
Finding the domain and range of a piecewise function where each segment is linear.
Worked example: domain & range of step function - Khan Academy
Finding the domain and range of a piecewise function that is constant in each segment. Such functions are called "step functions."
