Encourage students to make connections between graphs and domain and range written in inequality and interval notation.Students will match the graph of a function to another graph with the same domain and range. domain of log(x) (x^2+1)/(x^2-1) domain; find the domain of 1/(e^(1/x)-1) function domain: square root of cos(x) Graph: You can draw a continuous function without lifting your pencil from your paper. See Figure 6. Graph: A discrete graph is a series of unconnected points (a scatter plot). Even though they are represented differently, the above are the same function, and the domain of the function is x = {2, 3, 5, 6, 8} and the range is y = {4, 8, 2, 9, 3}. Students Advance from low D's to A's in fewer lessons at lower costs! The graph appears as dots. The domain and range of a function is all the possible values of the independent variable, x, for which y is defined. The range is all real y ≥−3. The range is all real y ≥−3. While driving to Florida, Sophia averaged 72 m.p.h. Donate Login Sign up. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values. Play this game to review Algebra I.
