Find the Domain of the Function $\{ x \mid x > 0 \} , \text { or } ( 0 , \infty )$

question 189

Short Answer

Find the domain of the function.
-f(x)=-7 x+7
A) $\{ x \mid x > 0 \} , \text { or } ( 0 , \infty )$
B) all real numbers, or $( - \infty , \infty )$
C) $\{ x \mid x \neq 0 \} , \text { or } ( - \infty , 0 ) \cup ( 0 , \infty )$
D) $\{ x \mid x > - 7 \} , \text { or } ( - 7 , \infty )$

• A) \(\{ x \mid x > 0 \} , \text { or } ( 0 , \infty )\)
• B) all real numbers, or \(( - \infty , \infty )\)
• C) \(\{ x \mid x \neq 0 \} , \text { or } ( - \infty , 0 ) \cup ( 0 , \infty )\)
• D) \(\{ x \mid x > - 7 \} , \text { or } ( - 7 , \infty )\)
