Find domain and range of piecewise functions.
Find the domain and range of a piecewise function given its formula.
The domain of any function is all the values that x can be for that function.
Need to calculate the domain and range of a graphed piecewise function.
An understanding of toolkit functions can be used to find the domain and range of related functions.
And thanks to the internet it s easier than ever to follow in their footsteps or just finish your homework or study for that next big test.
A piecewise function can be graphed using each algebraic formula on its assigned subdomain.
Piecewise functions let us make functions that do anything we want.
So the domain of this this is a review.
Piecewise functions are special functions that have different parts with unique rules for each part.

G of x is defined by a a line or the line changes depending what interval of x we re actually in.
A doctor s fee is based on the length of time.
And so let s think about its domain and then we ll think about its range.
The domain all the values that can go into the function is all real numbers up to and including 6 which we can write like this.
So we have a piecewise linear function right over here for different intervals of x.
For many functions the domain and range can be determined from a graph.
