Answer:
C. f(x)=3(1/2)^x
Step-by-step explanation:
standard form of a function is f(x)=ab^x
a should be 3, or the y value where the x value is 0
the b value is 1/2 because that's the rate of change
For this case we have:
The area of the piece of fabric is given by 
Where
Substituting in the formula of the area we have:
Thus, the area of the piece of fabric is given by:
