Two functions f and g are defined below:
space, g, left parenthesis, t, right parenthesis, equals, 4, t
space, f, left parenthesis, n, right parenthesis, equals, minus, 3, n, start superscript, 2, end superscript, minus, 7, n, minus, 3, left parenthesis, g, left parenthesis, n, right parenthesis, right parenthesis
What is the value of g, left parenthesis, f, left parenthesis, minus, 1, right parenthesis, right parenthesis?
