A set of ordered pairs, like the ones shown, represents a function only if each of the first coordinates is not repeated.

For example {(2, 5), (7, 8)} is a function, but {(2, 3), (6, 8), (2, -1)} is not because 2 is repeated.

We can check that each set of pairs we are given, are functions.



The inverses of each of these sets would be :

<span>{(–2, –1), (4, 0), (3, 1), (14, 5), (4, 7)}         4 repeats

{(2, -1), (4, 0), (5, 1), (4, 5), (2, 7)}             4 and 2 repeat

{(3, -1), (4, 0), (14, 1), (6, 5), (2, 7)}          no repetition of 1st coordinates

{(4, -1), (4, 0), (2, 1), (3, 5), (1, 7)}             4 repeats
</span>


So only the inverse of <span>{(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2)} is also a function</span>

Step-by-step explanation:

We know that Scientific notation is a way to write a very large or a very small number in the product of a decimal form of number [generally between 1 and 10] and powers of ten.

Given number : 0.00023

In scientific notation 0.00023=2.3\times\frac{1}{10000}=2.3\times10^{-4}

Therefore, In scientific notation  0.00023=2.3\times10^{-4}
