Question 939701: How would I solve this....
The table shows the cost y(in $) of x pounds of sunflower seeds.
Table : pounds,x/ costy,y
2 2.80
3 ?
4 5.60
A) What is the missing y-value that makes the table represent a linear functions? I got 4.2
B)Write a linear function that represents the cost y of x pounds of seeds.
C) What is the initial value of the function?
D)Does the function have a maximum value?Explain
-Thank you if you do solve it and thanks for taking the time to solve it :)

You can put this solution on YOUR website! The table shows the cost y(in $) of x pounds of sunflower seeds.
Table : pounds,x/ costy,y
2 2.80
3 ?
4 5.60
A) What is the missing y-value that makes the table represent a linear functions? I got 4.2
correct
-------------
B)Write a linear function that represents the cost y of x pounds of seeds.
f(0) = 0
slope = 2.8/2 = 1.4
y = 1.4x
========================
C) What is the initial value of the function?
f(0) = 0
---------------
---------------
D)Does the function have a maximum value?Explain
No, because it has a positive slope it will increase indefinately as x increases.
===================
