Domain And Range Of Piecewise Functions Examples
X 2 for x 0.
Domain and range of piecewise functions examples. The domain all the values that can go into the. Graph the piecewise function shown below. When x is more than 2 and less than or equal to 6 it gives the line 10 x.
It looks like this. So the domain of this this is a review. Pieces of different functions sub functions all on one graph the easiest way to think of them is if you drew more than one function on a graph and you just erased parts of the functions where they aren t supposed to be along the x s.
We can input any other value of 𝑥 so the domain of this function is ℝ 0. Finding the domain and range. 5 for 0 x 2.
Piecewise functions or piece wise functions are just what they are named. Learn how with this free video lesson. Let s go ahead and simplify this graph now so we can analyze it for its domain and range.
Since all values of x extend in both directions the domain would be all real numbers or. And so let s think about its domain and then we ll think about its range. Using the graph determine its domain and range.
For the function above the domain is left 1 1 right but the function definition on left 1 0 right is different from the function definition on left 0 1 right. This is an example of a function defined piecewise which means that the function definition is different on different parts of its domain. 1 per month helps.
