Answer

Final Answer: The value of the definite integral from b to 0 of the function f(x) is $\boxed{11.304}$

Steps

Step 1 ：Given the areas A, B, C, and D as 1.275, 2.497, 5.787, and 1.745 respectively.

Step 2 ：The definite integral from b to 0 of the function f(x) is the sum of these areas.

Step 3 ：Calculate the sum: $1.275 + 2.497 + 5.787 + 1.745 = 11.304$

Step 4 ：Final Answer: The value of the definite integral from b to 0 of the function f(x) is $\boxed{11.304}$
