Solution Steps

Step 1: Determining the Domain

The domain of the given relation is the set of all first elements from the ordered pairs. Thus, the domain is \(\{11, 20, 42, 57\}\).

Step 2: Determining the Range

The range of the given relation is the set of all second elements from the ordered pairs. Thus, the range is \(\{-7, 4, 5\}\).

Step 3: Checking if the Relation Represents a Function

The relation does not represent a function because there exists at least one input (domain element) that is associated with more than one output (range element).

Final Answer:

Domain: \(\{11, 20, 42, 57\}\), Range: \(\{-7, 4, 5\}\), Is Function: No

Question 14 (1 point) When the concentrations of reactant molecules are increased, the rate of reaction increases. The best explanation for this phenomenon is that as the reactant concentration increases, the average kinetic energy of molecules increases. the frequency of molecular collisions increases. the rate constant increases. the activation energy increases. the order of reaction increases. Question 15 (1 point) 18 The following mechanism has been suggested for the reaction: H2O2 + 2 H+ + 2 I- → I2 + 2 H2O H2O2 + I- → HOI + OH- OH- + H+ → H2O HOI + H+ + I- → I2 + H2O Slow Fast Fast Identify all intermediates included in this mechanism.
