Answer:
Step-by-step explanation:
answer B
since for all real positive r, r^x >0
The unique function who give a negative answer is f(x)=-3* 2^x
X=2W+1-1/Y
YOU SUBTRACT 2/Y TO START TO GET X ALONE.
WHICH WOULD MAKE IT 2X=4W+2-2/Y.
THEN YOU MUST DIVIDE BOTH SIDE BY TO FINISH GETTING X ALONE WHICH WOULD GIVE YOU YOUR ANSWER
Answer:

Step-by-step explanation:
Given the equation

Divide both sides by 

Simplify

Add 9 to both sides
