Answer:
We will see that g(x) is a reflection over the y-axis of f(x).
How does a reflection work?
For a given function f(x), we can define:
A reflection over the x-axis as: g(x) = -f(x)
A reflection over the y-axis as: g(x) = f(-x).
In this case we have:
f(x) = 0.7*(6)^x
g(x) = 0.7*(6)^-x = f(-x)
So is ratter easy to notice that g(x) is a reflection over the y-axis of f(x), so the correct option is:
"g(x) is the reflection of f(x) over the y-axis."

Find numbers.
w - width
2w - length (l)
30 cm - perimeter
w + w + 2w + 2w = 6w - perimeter
The equation:
6w = 30 divide both sides by 6
w = 5 cm
2w = 2(5) = 10
l = 10 cm
The area of a rectangle: A = lw.
Substitute:
A = (5)(10) = 50
B. C(n)=0.75n-0.25
C. C(n)=1.0n
D. C(n)=0.75n
Answer:
B. C(n)=0.75n-0.25
Step-by-step explanation:
Given : Cost of one candy = $0.75
There is a coupon of $0.25 off on total purchase .
To Find : Write a function rule for the cost of n pieces of candy.
Solution :
Since we are given that total candies bought = n
Cost of one candy = $0.75
Cost of n candy = $0.75n
So, cost of total purchase = $0.75n
Since on total purchase there is a off of $0.25
So, cost of total purchase after off will be $0.75n -$0.25
⇒C(n)= 0.75n-0.25
Where C(n) denotes the total cost after getting off
Hence Option B is correct.
A function rule for the cost of n pieces of candy is C(n)= 0.75n-0.25
