Answer:

Step-by-step explanation:

The average rate of change of function f(x) from x = a to x = b is

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

Here we have

a = -1

b = 2

f(a) = f(-1) = 1

f(b) = f(2) = 64

$\dfrac{f(b) - f(a)}{b - a} =$

$= \dfrac{f(2) - f(-1)}{2 - (-1)} =$

$= \dfrac{64 - 1}{2 + 1}$

$= \dfrac{63}{3}$

$= 21$

HELP ASAP!! Identify the matrix transformation of ΔPQR, which has coordinates P(−5, −2),Q(−6, −3), and R(−2, −3), for reflection

podryga [215]

Answer:

Matrix transformation = $\left[\begin{array}{ccc}-1&0\\0&1\end{array}\right]$

Vertices of the new image: P'= (5,-2), Q'= (6,-3), R'= (2,-3)

Step-by-step explanation:

Transformation by reflection will produce a new congruent object in different coordinate. Reflection to y-axis made by multiplying the x coordinate with -1 and keep the y coordinate unchanged. The matrix transformation for reflection across y-axis should be: $\left[\begin{array}{ccc}-1&0\\0&1\end{array}\right]$ .

To find the coordinate of the vertices after transformation, you have to multiply the vertices with the matrix. The calculation of the each vertice will be:

P'= $\left[\begin{array}{ccc}-1&0\\0&1\end{array}\right]$ $\left[\begin{array}{ccc}-5\\-2\end{array}\right]$ = (5,-2)
