Question

PLEASE HELP!!! This is a last minute homework help!!!
A cost function c(x) for producing x number of units: c(x) =20x+150
a) sketch the cost function c(x) from x=0 to x=50

Answer 1

surely you recognize that this is a linear function. So, plot any two points
(pick two values of x and calculate y)
draw a line between the points and extend it both ways. That is the graph.

If still unsure, google "linear function" or, what the heck, study your textbook a little.

Answer 2

x = 0

c = 20 • 0 +150 = 0 + 150 = 150


x = 50

c = 20 • 50 +150 = 1000 + 150 = 1150


Draw Cartesian coordinate system x , c(x)

Mark points x = 0 , c = 150 and x = 50 , c = 1150 and draw straigth line between the points.

Answer 3

hey Bosnian, thanks but do you mean by c is y coordinate and x is x coordinate

Answer 4

In Cartesian coordinate system horizontal coordinate is called abscissa.

Vertical coordinate is called ordinate.

The coordinates do not necessarily have to be x and y.

In this case abscissa is x , ordinate is c.
