Work the Exercise $f(x)=1.72 \ln (x)+16(x \geq 1)$ , Where $x=1$ Corresponds to the Year 2001

Work the exercise.
-In a certain type of specialty store, the rate of sales (in billions of dollars per year) is approximately $f(x) =1.72 \ln (x) +16(x \geq 1)$ , where $x=1$ corresponds to the year 2001. Find the function $F(x)$ that gives total sales between the year 2001 and year $x$ .

A) $F(x) =1.72 x \ln (x) +14.28 x-14.28$
B) $F(x) =1.72 x \ln (x) -14.28 x+14.28$
C) $F(x) =-1.72 x \ln (x) +14.28 x-14.28$
D) $F(x) =-1.72 x \ln (x) +17.72 x-17.72$
