Answer: Not proportional
=======================================================
Explanation:
Let's assume the two fractions are equal.
If so, then,
The last equation is false, so the first equation is false.
Therefore, the two ratios are <u>not</u> proportional.
-------------
Another approach:
Calculate the decimal value of each fraction
The two ratios result in different decimal values, so the two ratios are not equal, aka not proportional.
Using a graph tool
see the attached figure
<span>let's graph all the cases to verify the answer
case A) f(x)=(3</span><span>^x)-2
case B) </span>f(x)=(4^x)-2
case C) f(x)=4^(x-2)
case D) f(x)=4^(x-2) +2------> this is the solution
the answer is the option D
