Google is good for this, all you have to do is type in the question like that and it should work :)
But the answer is 72.5% I do believe
If 6 also had the -2 exponent answer would be D if not then A
2/3(6x+3)
2/3 x 3(2x+1)
2(2x+1)
4x+2
Therefore your answer is 4x+2
Total amount = Pe^(rt)
where
P=principal
e=2.7182818284...
r=0.035
t=3 (years)
Total amount
= 7565(e^(0.035*3)
=$ 8402.53
Its a graph linear i believe
