Give the domain and range of the relation A The domain is 7

Give the domain and range of the relation. A. The domain is (-7, 0) union (0, 7). The range is (-3, 0) union (0, 3). B. The domain is (-infinity, infinity). The range is (-infinity, infinity). C. The domain is (-10, 10). The range is (-3, 3). D. The domain is (-infinity, -7) union (7, infinity). The range is (- infinity, -3) union (3, infinity).

Solution

domain means values x taking in graph. so if we extrapolate the graph, x will take values from -infinity to +infinity.

range means values y taking in graph. it is clear that y can take values from - infifnity to +infifnity

so correct option is B
