Complete the statement f(3) is

Answered by maham237 @



F(3) is asking us "What output do I get with 3 as the input?". Looking at the Domain (all possible inputs) we see that 3 is indeed a possible input so that part is ok. Checking the Range (all possible outputs) we see that an input of 3 gives one and only one output (incidentally since this is true of all inputs, this is a function in 'x'). The only output that we get with an input of 3 is -1.
