The correct answer is Choice B.
Substitute $x=1$ into the given function to find $f(1)$.
Choice A is incorrect because $f(1)$does not necessarily equal 1.
Choice C is incorrect and may be the result of miscalculating $f(1) $ as$2(1)(3)-(1)(2)+4 $, not $2(1^3)-1^2+4$.
Choice D is incorrect and may be the result of miscalculating $f(1)$ as$2+1+3-1+2+4$, not $2(1^3)-1^2+4$.
