    we have these subsequent values: \[x = 1 \to y = 3 \times {1.1^1} = 3 \times 1.1 = 3.3\]

    \[x = 2 \to y = 3 \times {1.1^2} = 3 \times 1.21 = 3.63\]

    \[x = 3 \to y = 3 \times {1.1^3} = 3 \times 1.331 = 3.993\]

    finally: \[x = 4 \to y = 3 \times {1.1^4} = 3 \times 1.4641 = 4.3923\]

    from your table, I see that when x=2, then y= 3.5, whereas from our computation we see that when x02 then y= 3.63, so what can you conclude?

    I think that y=3.5 is incorrect, since when x=2 we have y=3.63 am I right?
