option C is correct.
<u>Step-by-step explanation:</u>
If a function is defined as
where, a>0, then the range of the function is greater than 0.
.... (1)
Option A: Using inequity (1),
Multiply both side by 3.
The range of first function is y>0. Therefore option A is incorrect.
Option B: Using inequity (1),
Multiply both side by 2.
The range of second function is y>0. Therefore option B is incorrect.
Option C: Using inequity (1),
Multiply both side by -1.
Add 3 on both the sides.
The range of first function is y<3. Therefore option C is correct.
Option D: Using inequity (1),
Subtract 3 from both the sides.
The range of second function is y>-3. Therefore option D is incorrect.
