Question

1. Graph the function y= 2/x. Draw a chart to show at least four ordered pairs that are on the graph.

Answer 1

Y = 2/x

x must not have the value of 0 because x is used as a denominator. 
A denominator must not have a value of 0 because the overall value of the fraction is undefined.

x may be any positive or negative integer.

x = 1
y = 2/1 = 2 ⇒ (1,2)

x = 2
y = 2/2 = 1 ⇒ (2,1)

x = 3
y = 2/3 = 0.67 ⇒ (3, 2/3)

x = -1 
y = 2/-1 = -2 ⇒ (-1,-2)

x = -2
y = 2/-2 = -1 ⇒ (-2, -1)

x = -3 
y = 2/-3 or -0.67 ⇒ (-3, -2/3)
