Find the average rate of change for problems 1-3: X. X^2+7 2. 11 3. 16 4. 23 5. 32 6. 43 1) what is the average rate of change b
miv72 [106K]

Answer:

(1)7 (2)9 (3)6

Step-by-step explanation:

\left|\begin{array}{c|cc}X&f(X)=X^2+7\\--&-----\\2&11\\3&16\\4&23\\5&32\\6&43\end{array}\right|

(1)The average rate of change between x=2 and x=5

\dfrac{dy}{dx} =\dfrac{f(5)-f(2)}{5-2} =\dfrac{32-11}{3} =\dfrac{21}{3} =7

(2)The average rate of change between x=3 and x=6

\dfrac{dy}{dx} =\dfrac{f(6)-f(3)}{6-3} =\dfrac{43-16}{3} =\dfrac{27}{3} =9

(3)The average rate of change between x=2 and x=4

\dfrac{dy}{dx} =\dfrac{f(4)-f(2)}{4-2} =\dfrac{23-11}{2} =\dfrac{12}{2} =6

If a translation of <img src="https://tex.z-dn.net/?f=T_%7B-3%2C-8%7D%20%28x%2Cy%29" id="TexFormula1" title="T_{-3,-8} (x,y)" al
nydimaria [60]

The y-coordinate of B' after the translation is -6

<h3>How to determine the y-coordinate of B'?</h3>

From the graph, the coordinate of B is given as:

B = (1,2)

The translation T_{-3,-8}(x,y) means:

(x,y) ⇒ (x - 3, y - 8)

So, we have:

B' = (1 - 3, 2 - 8)

Evaluate the difference

B' = (-2, -6)

Remove the x-coordinate

B' = -6

Hence, the y-coordinate of B' is -6
