Answer:
a = 300
Step-by-step explanation:
so 5/a=60
multiply 60 by 5
So if 18 + x =43, then what you need to do is
18 + x =43
-18 -18
——————
x = 25
because whatever you do to one side, you need to do to the other
Answer:
domain is x axis range is the y axis
Step-by-step explanation:
Answer:
I assume that the function is:
![f(x) = \frac{1}{4}*8^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B1%7D%7B4%7D%2A8%5Ex)
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](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B1%7D%7B4%7D%2A8%5Ex)
then:
![g(x) = -f(-x) = -\frac{1}{4}*8^{-x}](https://tex.z-dn.net/?f=g%28x%29%20%3D%20-f%28-x%29%20%3D%20%20-%5Cfrac%7B1%7D%7B4%7D%2A8%5E%7B-x%7D)
Now we can graph this, to get the graph you can see below:
