Given:

The set is

\{(3,4),(4,4),(8,-1)\}

To find:

The correct option for the given set which represents the quality that is not in the given set.

Solution:

We have,

\{(3,4),(4,4),(8,-1)\}

It is the set of ordered pairs. So, it is a relation.

For each x-value there is a unique y-value value. So, it is a function.

All elements are real numbers but they not distinct and they are in ordered pairs. So, the given set is not a set of real numbers.

In one to one functions each image has exactly one preimage and each preimage has exactly one image.

In the given set 4 has two preimages 3 and 4. So, the given set is not a one to one function.

Therefore, the correct options are C and D.

Answer:

i). x³ + 9x² + yz - 15

ii). -21m³np - 8p⁵q + mnp + 4mn + 100

Step-by-step explanation:

Question (38)

i). Two expressions are -5x² - 4yz + 15 and x³+ 4x²- 3yz

  By subtracting expression (1) from expression (2) we can the expression by addition which we can get expression (1).

 (x³+ 4x²- 3yz) - (-5x² - 4yz + 15) = x³ + 4x² - 3yz + 5x² + 4yz - 15

                                                    = x³ + 9x² + yz - 15

ii). -15m³np + 2p⁵q - 6m³pn + mnp + 4mn - 10qp⁵+ 100

  = (-15m³np - 6m³np) + (2p⁵q - 10qp⁵) + mnp + 4mn + 100

  = -21m³np - 8p⁵q + mnp + 4mn + 100

The "1" beside the 8, is the tenths spot so you would round that part of the number.

Therefore the answer would be:
