A function is a rule that assigns to each input exactly one output. In a graph, the input is the x-value, and the output is the y-value.

Which graph(s) do not represent a function?

Consider the relation shown in the figure. Which ordered pairs show that the relation is not a function?

• (0,-2) and (0,1)

• (0,1) and (2,1)

• (1, 2) and (3,4)

• None, because this mapping is a function

Which graphs represent functions?

• Graph B and C only

• Graph B, C and D only

• Graph A only

• All of the graphs represent functions.

Which has a positive slope?

• Only Function 1

• Only Function 3

• Both functions 1 & 3

• Both functions 2 & 3

Which function has a greater y-intercept, and why?

• Function 2 has a greater y-intercept because 5 > 3.

• Function 1 has a greater y-intercept because 5 > 3.

• Function 2 has a greater y-intercept because -1/2 > -3.

• Function 1 has a greater y-intercept because -1/2 > -3
