Here are the two functions that I wrote...

# This function draws a polygon
def polygon(length_of_side, number_of_sides):
     for i in range (number_of_sides):
        turtle.forward(length_of_side)
        turtle.left(360/number_of_sides)

# This function positions the turtle
def position(x,y):
     turtle.penup()
     turtle.setposition(x,y)
     turtle.pendown()

Later in the code you will see things like...

position(100,100)
polygon(100,5)


If you compare these back to the two functions you will see that the 
first of these
sets the POSITION of the turtle in x and y coordinates.   The second of 
these draws
a POLYGON with the first argument defining the size of the polygon and 
the second one
defining the number of sides.

turtle.circle(100)

is similar but only has one argument, the size of the circle.


Your job is to change the arguments to the position, polygon, and circle 
functions
to meet the requirements of the exercise.

  For example -- try this

position(125,-10)
polygon(50,5)

and see what happens to your pentagon.
