Question

f(x)/x represents the average cost of producing 1 kilogram of the chemical when x kilograms are made. This problem asks you to visualize these averages graphically.
We can represent f(4)/4 as the slope of a line. Through what points does this line extend?
( ?, ? ) and ( ?, ? )

Answer 1

all we know is the slope of the line.
obviously it costs 0 to produce 0 kilos. so it passes through the origin.
we can't say what else it passes through.

Answer 2

ok one of the points is (0,0) the problem is the next point

Answer 3

there is not enough information to determine the other point.

Answer 4

all i know so far is that the other point is (4.?)
that is my problem

Answer 5

you could say it passes through (4,f(4))

Answer 6

so the two points are (0,0) and (4, f(4) )
