Find the range of the function.
-$$f ( x ) = 7 x - 5$$
A) $( - 5 , \infty )$
B) $[ 0 , \infty )$
C) $( - \infty , \infty )$
D) $[ - 5 , \infty )$

Question

Quizplus · Accepted Answer

The function $f(x) = 7x - 5$ is a linear function with a slope of 7 and a y-intercept of -5. Since the slope is not zero, the function will take on every possible value as $x$ ranges over all real numbers. Therefore, the range is all real numbers, $( - \infty , \infty )$.
