For the pair of functions, find the indicated sum, difference, product, or quotient.
-$$f ( x ) = \sqrt { 7 x + 4 } , g ( x ) = \frac { 1 } { x }$$
Find $( f - g ) ( x )$
A) $\frac { 1 } { \sqrt { 7 x + 4 } - x }$
B) $\frac { 1 } { x } - \sqrt { 7 x + 4 }$
C) $\sqrt { 7 x + 4 - \frac { 1 } { x } }$
D) $\sqrt { 7 x + 4 } - \frac { 1 } { x }$

Question

Quizplus · Accepted Answer

The difference $(f - g)(x)$ is found by subtracting $g(x)$ from $f(x)$, resulting in $\sqrt{7x + 4} - \frac{1}{x}$.
