Answer:

A. right 2, up 3

Step-by-step explanation:

We have that,

The function is transformed to .

We see that,

The function f(x) is translated 2 units to the right and 3 units upwards to obtain the function g(x).

So, the correct transformation is 'right 2, up 3'.

option A is correct.

Answer:

216

Step-by-step explanation:

(g∘f)(2) = g(f(2)) = g(2·2+2) = g(6) = 6³ = 216

Please note that the ∘ operator is very different from the • operator. Your problem statement asks one thing, but the picture asks something entirely different.

Answer:

$g(x) = 3(x - 12)^{2} - 5$

Step-by-step explanation:

Horizontal translations = f(x ± h)

Reflection over the x-axis = - f(x)

For the function $f(x) = - 3(x - 4)^{2} +5$ , translating the parabola 8 units to the right means the horizontal shift of the graph, adding (- 8) to the h input. This is represented by: $g(x) = - 3(x - 12)^{2} +5$ .

Next, flipping the graph over the x-axis represent a reflection. Since we currently have a negative coefficient for the value of a, then the opposite of a negative coefficient is a positive coefficient.

Therefore, the rightward horizontal translation of 8 units, and the reflection of the graph over the x-axis is represented by:

$g(x) = 3(x - 12)^{2} - 5$

For your reference, the three images below shows the transformations on the graph. The first image is the original function (in red parabola). The second image represents the reflection over the x-axis (green parabola). The third image shows the horizontal shift, 8 units to the right (blue parabola). If you take note of the varying values in vertices, (h, k ) for the three graphs, you'll see that the original vertex was (4, 5) and the new vertices for the transformations are (4, -5) for the reflection and (12, -5) for the shift.
