Then, use each function and each of their corresponding intervals to graph each piece of the piecewise function. Any points omitted by the interval are not graphed by the function, as they will typically be inc
However, in a piecewise-defined function, we would need to examine the values for y when both evaluating and graphing the function. Take a look at the graph for the example we used previously: {eq}f(x)= \left\{\begin{matrix} x^2\,,for\, x<-1\\3x-1\,,for\,x\geq -1 \end{...
Learning Outcomes Write piecewise defined functions. Graph piecewise-defined functions.Sometimes, we come across a function that requires more than one formula in order to obtain the given output. For example, in the toolkit functions, we introduced the absolute value function ...

In the plot windows below, create graphs points by clicking or dragging in either plot window. The same points are shown in both graphs. The graph on the left will interpolate a polynomial function in the lowest degree possible, whereas the graph on the right will interpolate a cubic spline...
A piecewise function is a type of function that is used to graph several functions that are defined in different interval values in the x-axis. In graphing a piecewise function, the first thing we need to know is how to graph each given function. ...
For example, the cosinefunctioncan be replaced in the infinite series by apiecewiselinear "zigzag"function. WikiMatrix The relationship between the walking speed and the exercise intensity is expressed as apiecewiselinearfunctionbased on a known value. ...
Example 1: Determining the Domain and Range of a Piecewise-Defined Function given Its Graph Determine the domain and the range of the function 𝑓(𝑥)=6,𝑥<0,−4,𝑥>0. Answer We recall that the domain of a function is the set of all input values of the function and the...
SowTionAgain we will evaluate each using both the definition of and its graph.1. As approaches 1 from the left, we see that approaches 1 . Therefore .2. As approaches 1 from the right, we see that again approaches 1 . Therefore .3. The limit of as approaches 1 exists and is 1 ,...
