Mathematics
1 answer:
Pie3 years ago
8 0

Answer:

The relation is <u>not</u> a function.

Step-by-step explanation:

A function is a relation in which no two ordered pairs have the same input  and different outputs. Whenever you're trying to determine whether a given relation is a function, observe whether each input corresponds with <u><em>exactly</em></u> one output.

In this case, the answer is no.  The input value of 10 corresponds with two output values, 4 and 20.  It only takes one input value to associate with more than one output value to be <u>invalid</u> as a function.

Therefore, the given relation is <em><u>not</u></em> a function.

256,000-2.56*100,000
Since there are 6 digits in 256,000, it is 2.56*100,000 becuase 100,000 also has 6 digits.
2.56*100,000=2.56*10^5
Since there are 5 zeroes in 100,000, it is 10^5.
256,000=2.56*100,000=2.56*10^5
First box: 100,000
