Calculate the rate of change for the following data:

Licemer1 [7]

Given:

The table of values.

To find:

The rate of change.

Solution:

From the given table it is clear that the rate of change is constant and function passes through two points (-1,5) and (2,-4). So, the rate of change is

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{-4-5}{2-(-1)}$

$m=\dfrac{-9}{2+1}$

$m=\dfrac{-9}{3}$

$m=-3$

So, the rate of change is -3.

Therefore, the correct option is C.

D = √(x2 - x1)^2 + (y2 - y1)^2) =
= √(6 + 1)^2 + (-2 - 4)^2) =
= √ (7^2 + 6^2) =
= √(49 + 36) =
= √85

Answer:

x²+8x+16

Step-by-step explanation:

f(x) = (x+4)²

= (x+4)(x+4)

= x² + 4x + 4x + 16

= x² + 8x + 16
