Substituting $x=2.5$ in the function gives us:
$f(2.5)=3.3 e ^ {-1.8 \times 2.5} = 0.03684 \approx 0.037$ rounded to 3 decimal places, therefore the answer is B.

What Is the Value of the Function f(x)=3.3e−1.8xf ( x ) = 3.3 e ^ { - 1.8 x }f(x)=3.3e−1.8x

What Is the Value of the Function $f ( x ) = 3.3 e ^ { - 1.8 x }$
