1.What Is Function?

1.What is function?

 

Answer:

Function is a relation where the first elements x of each ordered pair (x, y) are not repeated.

Step-by-step explanation:

Examples of ordered pairs of a function:

{(2,3), (3,4), (4,5) }

The first elements are 2, 3, 4.

The second elements are 3,4,5.  

A second element may be repeated but not the first element to be considered a function.

6. 25 - r² = 4r 7. 3x(x - 2) =-7 8.½ (h-6)=0 9. (x + 2)² = 0 0. (w – 8)(w + 5) = 14   Answer and Step-by-step explanation: 6. 25 - r² = 4r −r²−4r+25=0 Quadratic 7. 3x(x - 2) =-7 3x²−6x+7=0 Quadratic 8.½ (h-6)=0 1/2h-3=0 The degree of the equation is 1 so its not a quadratic equation. 9. (x + 2)² = 0 x²+4x+4=0 Quadratic 10. (w – 8)(w + 5) = 14 w²−3w−54=0 Quadratic #JuneChallenge

Explain What Is Meant By The Statement "Plants Don\T Need Us But We Need Plants"

Explain what is meant by the statement "Plants dont need us but we need plants"   Plants can survive without humans, while humans cannot live without plants. Why? One of the reasons is that the carbon dioxide we exhale are recycled by plants to oxygen. Without plants well have no source of oxygen to inhale, that can lead us to death, because our cellular processes are oxygen-dependent. Plants can also be a source of food which provides many nutritional values, keeping us healthy and supplies necessary nutrition in the body. Plants can survive without humans because they are mostly dependent on the environment such as soil, air and sunlight.
