Find the range of the function given in graph
None of these
Range of a function is set of all values y take in the graph of a function. We can see in the given graph that all the values from negative infinity to zero are covered. So (−∞,0] is part of the range. Now the only value above 0, which is also part of the range is 1. Combining these two we get the range as (−∞,0]∪1
