• Denny is right because the function y=2x is linear as it can be graphed as a straight line.
• Odette is right because the function y=2x is nonlinear as it cannot be graphed as a straight line.
• Both are right because the function y=2x can be both linear and nonlinear.
• Both are wrong because the function y=2x is neither linear nor nonlinear.

Shannon has a summer job working as a lifeguard at the community pool. The graph shows the relationship between the number of hours Shannon worked and the amount of money, in dollars, that Shannon earned. Select the equation that represents the amount of money, m, in dollars, that Shannon earned by working h hours.

• m = 10h

• m = 15h

• m = 11h

• m = 7h

Does the set of ordered pairs { (1, 1) , (2, 1), (3, 3) , (4, 3) , (5, 3) } define a function?

• Yes, because each input has only one output.

• No, because two different x-values are paired with 1.

• No, because 3 is paired with 3 different y-values.

• No, because 1 is paired with itself.
