Wich graph is the result of the reflection f(x) =1/4(8)^x across the y axis and then across the x- axis
Snowcat [4.5K]

Answer:

I assume that the function is:

f(x) = \frac{1}{4}*8^x

Now let's describe the general transformations that we need to use in this problem.

Reflection across the x-axis:

For a general function f(x), a reflection across the x-axis is written as:

g(x) = -f(x)

Reflection across the y-axis:

For a general function f(x), a reflection across the y-axis is written as:

g(x) = f(-x)

Then a reflection across the y-axis, and then a reflection across the x-axis is just:

g(x) = -(f(-x)) = -f(-x)

In this case, we have:

f(x) = \frac{1}{4}*8^x

then:

g(x) = -f(-x) =  -\frac{1}{4}*8^{-x}

Now we can graph this, to get the graph you can see below:

1) what is the value of x ?
Vikentia [17]

Answer:

a). x = 9

b). m∠ABC = 27°

c). m∠CBD = 153°

Step-by-step explanation:

1). Property of linear pair of angles states, "sum of linear pair of angles is 180°"

3x + (15x + 18) = 180°

18x + 18 = 180

18x = 180 - 18

18x = 162

x = 9

2). m∠ABC = 3x°

                   = 3×9

                   = 27°

3). m∠CBD = (15x + 18)°

                  = (15×9 + 18)°

                  = (135 + 18)°

                  = 153°
