Hello!
The graph, (2/5)^x is an exponential function.
Since there is not a negative symbol in the front of the function, options A and B are incorrect.
For option 3 to be correct, there would need to be a negative symbol in front of the exponent, x. 
So therefore, the answer option 4. (Also, I'll post a graph. :))
 
        
             
        
        
        
Answer:
3(x + 1) + 6 = 33
3x+3+6=33
3x+9=33
3x=33-9
3x=24
x=24/3
x=8
