f(x)=6(2x)
f left parenthesis x right parenthesis equals 6 left parenthesis 2 x right parenthesis

f(x)=12x
f left parenthesis x right parenthesis equals 12 superscript x baseline

f(x)=2(6)x
f left parenthesis x right parenthesis equals 2 left parenthesis 6 right parenthesis superscript x baseline

f(x)=6(2)x

Answer 1

f(x) = 6·2^x

Reason: y doubles as x increases by 1 (ratio 2), and f(0)=6, so the exponential model is 6·2^x.
