Domain And Range Of A Piecewise Function Graph
So the domain of this this is a review.
Domain and range of a piecewise function graph. Graph the piecewise function shown below. 2x for x 0. The domain of a piecewise defined function is the union of its subdomains.
1 for x 0. Make sure to leave the point of origin unfilled. So we have a piecewise linear function right over here for different intervals of x.
Need to calculate the domain and range of a graphed piecewise function. Learn how to determine the domain and range of a function given the graph of the function. Learn how with this free video lesson.
To graph the linear function we can use two points to connect the line. G of x is defined by a a line or the line changes depending what interval of x we re actually in. The range of a piecewise defined function is the union of the ranges of each subfunction over its subdomain.
We can find the domain of a function from its graph by considering the intersections of the curve with vertical lines. Using the graph determine its domain and range. And so let s think about its domain and then we ll think about its range.
Just make sure that the two points satisfy y 2x. Since the domain of a function is the set of all x values we will.
