Quizplus · Accepted Answer

To find $f(3.2)$, substitute $x = 3.2$ into the function $f(x) = 2x - 3x$. This simplifies to $f(3.2) = 2(3.2) - 3(3.2) = 6.4 - 9.6 = -3.2$. However, none of the options exactly match -3.2, suggesting a possible mistake in the transcription of the question or answer choices. Based on the provided options, there seems to be a misunderstanding, as the correct calculation does not match any of the given choices.
