Question 99987: Hello! The directions for this problem are to find the domain and graph the problem. The problem is {abs(x) + abs(y)<_ 1}
It would be read as "The absolute value of x plus the absolute value of y is less than or equal to 1."
Any help with solving this problem would be great. Thank you!

Question 101813: The crop yield, Y, (in bushels) for various amounts, x (in pounds per 100 square feet) of fertilizer used in 18 different plots of land is as shown in the table below. The graph of the data can be modeled by Y(x)=-0.017x^2+1.0765x + 3.8939.
Plot / Fertilizer (x) / Yield - Y(x)
1 0 4
2 0 6
3 5 10
4 5 7
5 10 12
6 10 10
7 15 15
8 15 17
9 20 18
10 20 21
11 25 20
12 25 21
13 30 21
14 30 22
15 35 21
16 35 20
17 40 19
18 40 19
based on the data and the quadratic model, what is the optimal amount of fertilizer to apply for maximum crop yield? Explain or show how you decided.
