Answer:

Step-by-step explanation:

The rate of change of a function in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b } = [ 0, 4 ]

From the graph

f(b) = f(4) = 75 and f(a) = f(0) = 15, thus

average rate of change = $\frac{75-15}{4-0}$ = $\frac{60}{4}$ = 15

The point (17,−9) is translated to the point (6,2). Select the description of the translation.

zubka84 [21]

Answer:

11 up , 11 left

Step-by-step explanation:

Given

$(17, -9)$ to $(6,2)$

Required

Determine the translation rule

Considering the x coordinates.

From 17 to 6

6 is to the left of 17.

Using the translation rule:

$x = x' + b$

$17 = 6 + b$

$17 - 6 = b$

$11 = b$

$b = 11$

<em>Hence: From 17 to 6 is 11 units left translation</em>

Considering the y coordinates.

From -9 to 2

2 is at the top -9.

Using the translation rule:

$y = y' + b$

$-9 = 2 + b$

$-9 - 2 = b$

$-11= b$

$b = -11$

The negative value impies a upward translation.

Hence: From -9 to 2 is 11 units up translation
