Please explain in detail

For the given x and t values in the top row of the following tables, the corresponding output values of functions f and g are shown in the rows below. 0 3 f (x) 9 Z 6 -4 -5 -9 -2 3 g(t) 3 0 3 2 -3 -5 a. Determine whether the following statements are true or false. Select an answer v | f is a function because for every value of x there is only one corresponding value of f(x). Select an answer v f is a function because for every value of f(x) there is only one corresponding value of x. Select an answer v g is a function because for every value of t there is only one corresponding value of g(t). Select an answer v g - is a function because for every value of g(t) there is only one corresponding value of t. b. Evaluate these expressions using the tables above. f 1( - 9 ) = Preview g(3) = Preview f(g(2)) = Preview f ' ( 2 ) = Preview f (g(3)) = Preview 9 ( f 1 ( - 4 ) ) = Preview
