question 92

Multiple Choice

Determine i) the domain of the function, ii) the range of the function, iii) the domain of the inverse, and iv) the range of
the inverse.
- $$f ( x ) = - 7 x - 4$$

• A) \(\mathrm { f } ( \mathrm { x } ) : \mathrm { D } = \{ \mathrm { x } \mid \mathrm { x } > - 7 \} , \mathrm { R }\) is all real numbers; \(\mathrm { f } ^ { - 1 } ( \mathrm { x } ) : \mathrm { D } = \{ \mathrm { x } \mid \mathrm { x } < - 7 \} , \mathrm { R }\) is all real numbers
• B) \(f ( x ) : D = \{ x \mid x > - 7 \} , R = \{ y \mid y > - 4 \}\); \(f ^ { - 1 } ( x ) : D = \{ x \mid x < - 7 \} , R = \{ y \mid y < - 4 \}\)
• C) \(f ( x )\) : D is all real numbers, \(R = \{ y \mid y > - 4 \}\); \(f ^ { - 1 } ( x )\) : \(D\) is all real numbers, \(R = \{ y \mid y < - 4 \}\)
• D) \(f ( x )\) : D is all real numbers, \(R\) is all real numbers; \(\mathrm { f } ^ { - 1 } ( \mathrm { x } )\) : \(D\) is all real numbers, \(R\) is all real numbers
