• A) \(\frac { 1 } { x } + 7\) Domain of \(f \circ g\) : all real numbers x except \(x = 0\)
• B) \(- \frac { 1 } { x + 7 }\) Domain of \(f \circ g\) : all real numbers x except \(x = - 7\)
• C) \(\frac { 1 } { x + 7 }\) Domain of \(f \circ g\) : all real numbers x except \(x = - 7\)
• D) \(\frac { 1 } { x } - 7\) Domain of \(f \circ g\) : all real numbers x except \(x = 0\)
• E) \(\frac { 1 } { x - 7 }\) Domain of \(f \circ g\) : all real numbers x except \(x = 7\)
