For Which Values Of K Is The Set Of Order Pairs {(2,4),(K, 6),(4,K)} A Function?

For which values of k is the set of order pairs {(2,4),(k, 6),(4,k)} a function?

 

Answer:

{k/k is a real number; k≠2 and k≠4}

Step-by-step explanation:

A relation is a function where  the first elements (x-coordinate) are not repeated.  However, the second elements (y-coordinates) can be repeated.

Given: {(2,4),(k, 6),(4,k)}

The first elements are 2, k, and 4.

For the set to be considered a function, 2 and 4 can not be repeated.

Therefore:

k/k is a real number; k≠2 and k≠4

When Cells Breakdown A Sugar Molecule Completely To Produce Chemical Energy (Atp), The Cells Need The Following Materials_________, A. Sugar And Oxyg

"When cells breakdown a sugar molecule completely to produce chemical energy (ATP), the cells need the following materials_________ a. Sugar and oxygen c. Sugar only b. Sugar and water d. Sugar and carbon dioxide "   Answer: d. Sugar and carbon dioxide Explanation: Photosynthesis is the process by which CO2 and H2O are used to make sugars and starches. During respiration, sugar is attenuated to CO2 and H2O, and in the process, ATP is made that can then be used for cellular work. Whereas solely chemical change cells will create sugar exploitation chemical process, all a need to be able to break down sugars they take in from their environment and turn it into energy to be employed in cellular work. Plants are sole chemical change organisms to possess leaves. A leaf could also be viewed as a reflector crammed filled with chemical change cells. The raw materials of a chemical process, water, and greenhouse emission, enter the cells of the leaf, and also the produc
