Why is
zloy xaker [14]

Answer:

Only natural numbers (i.e., non-negative integers) can be the exponents of variables in a polynomial.

Step-by-step explanation:

The exponent of variables in a polynomial should be natural numbers (0, 1, 2, 3, \dots.)

  • \sqrt{2\, x} is equal to \sqrt{2}\, x^{1/2}. In this expression, x is the variable. Its exponent is 1/2, which isn't a natural number.
  • On the other hand, \sqrt{2}\, x is equivalent to \sqrt{2}\, x^{1}. The exponent of variable x is 1, which is indeed a natural number.

\sqrt{2\, x} isn't a polynomial because the exponent of variable x isn't a natural number. On the other hand, \sqrt{2}\, x is indeed a polynomial over the set of real numbers.

The average rate of change is -5 per month

<h3>How to determine the average rate of change?</h3>

The interval is given as:

July to December

From the graph, we have:

July = 110

December = 30

The average rate of a function over the interval (a, b) is calculated as:

Rate = [f(b) - f(a)]/[b - a]

So, we have:

Rate = (30 - 110)/(December- July)

This gives

Rate = (30 - 110)/(12 - 7)

Evaluate

Rate = -16

Hence, the average rate of change is -5 per month
