The table below shows some input output pairs of two functions f and g that agree for the values that are given but some of their output values are missing t f t g t 0 0 0 15 0 5 0 5 30 45 1 3 1 3 60 2 2 75 2 7 2 7 90 105 4 4 Graph both functions and explain from the graph why f is invertible and g is not Come up with two real life situations that f and g could be representing Find and interpret the value f 4 in terms of these contexts 120 Complete the table in a way so that f could be invertible and so that g is definitely not invertible
