<h3>What is graph?</h3>Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The complete question is:
An Algebra II textbook manufacturer determines that its profit, in thousands of dollars, can be modeled by the following function, where x represents the number of Algebra II textbooks sold, in hundreds.
P(x) = 0.0013 +x -4.
Use a table of values to determine which graph represents the given situation. Number of Textbooks Sold (in hundreds) Number of Textbooks Sold (in hundreds) w. X. g 4
table for P(x) = 0.0013 +x -4.
x P(x)
0 -0.8949
1 0.3328
2 1.8125
3 3.6848
By the table value we can say that the root is in (3,4)
The graph which shows is (W).
