When using set notation we use inequality symbols to describe the domain and range as a set of values. If the parabola starts at y -4 and goes up then the range is -4. Now lets find the domain and range of a piecewise function adding the restrictions in the if statements.

Therefore on a graph the domain and range can be found by identifying the range of x and y-value variations. The graphs give us an idea of which values of x and which values of y are being taken. 5 for 0 x 2.

I need to be careful when graphing radicals. Domain and Range Name. This compilation of domain and range worksheet pdfs provides 8th grade and high school students with ample practice in determining the domain or the set of possible input values x and range the resultant or output values y using a variety of exercises with ordered pairs presented on graphs and in table format.

When x 0 fx becomes a quadratic function with a parabola that passes through the origin and -2 4. Where y would represent the range x would represent the domain and f would represent the. The domain does not include x 2 because of the open circle at x 2.

The only problem I have with this function is that I need to be careful not to divide by zero. It shows you how to identify the vertical as. Write the domain of the graph of the function.

Observe the graph of the given quadratic equation. The range is the set of possible output values which are shown on the y-axis. The range of an exponential function can be determined by the horizontal asymptote of the graph say y d and by seeing whether the graph is above y d or below y d.

The graph starts at y 0 and goes down heading. X 2 for x 0. Since it only applies.
