    it is not \(f(x)=2x\) since that would make \(f(5)=10\) but \(f(5)=2\)

    it is not \(f(x) = x - 3 \) since that would make \(f(6)=6-3=3\) but \(f(6)=4\)

    and it sure as hell is not \(f(x)=x-8\) since you are not subtracting 8 from the first number to get the second

    gotta be D you can check to see that if you double the first number, then subtract 8 from the result, you get the second number

    most of the answers to the last one don't even make logical sense, but the answer you are looking for is D an exponential function with a base bigger than one will eventually exceed any polynomial function
