Ket [755]2 years ago
8 0

The average rate of change for this function for the interval from x = 1

to x = 3 will be 8. Therefore option B is correct.

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

Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:

\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}

where when

x = x_1, y = y_1\\and \\x = x_2, y = y_2

The average rate of change can be calculated as;

From x=1 to x=3,

y = 2 and y = 18

Therefore, based on the table, when:

x_1 = 1 y_1 = 2 \\and \\x_2 = 3, y_2 = 18

Then:

\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}

\text{Average rate} = \dfrac{18 - 2}{3-1}\\\\\text{Average rate} = \dfrac{16}{2}\\\\\text{Average rate} = 8

Therefore option B is correct.

Ethan is thinking of a negative number that is lower than -4 and higher than
s2008m [1.1K]

When the number is odd and a multiple of 3, the number that Ethan is thinking of is -9.

<h3>How to illustrate the number?</h3>

In mathematics, a multiple is the product of any quantity and an integer. It should be noted that, for the quantities a and b, it can be said that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.

In this case, Ethan is thinking of a negative number that is lower than -4 and higher than -10 and his number is odd and a multiple of 3. The number is -9 since 9 is a multiple of 3.
