How would I use a logarithmic model (y = a + b ln x) for the information that is in the picture? X is the number of jackets so the 1000, 2000 3000 and so on and the Y can be either the price demand or the price supply.

An unknown number x is at most 10. which graph best represents all the values of x? number line graph with closed circle on 10 and shading to the right. number line graph with open circle on 10 and shading to the right. number line graph with open circle on 10 and shading to the left. number line graph with closed circle on 10 and shading to the left.
