Question

The range of $y=3.5x$ function is

• A. $(0,\infty )$
• B. $(3,\infty )$
• C. $(-\infty ,\infty )$

Answer 1

The correct option is C

$(-\infty ,\infty )$

Explanation for the correct option:

Find the range of the function:

Given the function $y=3.5x$
The domain of the function is $(-\infty ,\infty )$
The range is the output value $y$ for which the function exists.
The range also exists on the real values. The range of the function will also be $R=(-\infty ,\infty )$

Hence, option C is correct.
