Remember, there can be more than one answer!

We cannot evaluate the function at 1 because division by zero is undefined. Play free Games, Puzzles, Quizzes.

Note that the output of this function is always positive due to the square in the denominator, so the range includes only positive numbers. \[ f(x) = -x \; \text { if } \; x < 0 \nonumber \].

As a more extreme example, a functions inputs and outputs can be completely different categories (for example, names of weekdays as inputs and numbers as outputs, as on an attendance chart), in such cases the domain and range have no elements in common. The domain is the set of real numbers. To combine two intervals using inequality notation or set-builder notation, we use the word or. As we saw in earlier examples, we use the union symbol, \(\cup\),to combine two unconnected intervals. The smallest term from the interval is written first. There is also no x that can give an output of 0, so 0 is excluded from the range as well. First identify the input values. Also explore over 1 similar quizzes in this category.

Ask your question. Consider the relation {(0,7),(0,8),(1,7),(1,8),(1,9),(2,10)} . The only output value is the constant \(c\), so the range is the set \(\{c\}\) that contains this single element. It is the distance from 0 on the number line. This notation is extended to cover more general algebrainvolving variables: for example (x+ y) (x y). //-->,
