Domain: -∞<x<∞
Range: -∞<x<∞
X-Intercept: x=0
Y-Intercept: y=0
Increasing on the interval of 0<x<∞
Decreasing on the interval of -∞<x<0

When A=0, the graph equals y=0
- When A is greater than 1, it makes the graph skinnier than f(x)=|x|
- When A is less than 1 but greater than 0, it makes the graph fatter than f(x)=|x|
- When A turns negative, it flips the graph upside down.

-When B is greater than 0, it translates the graph to the right
- When B is less than 0, it translates the graph to the left

When C is greater than 0, the graph moves upwards
When C is less than 0, the graph moves downwards

Answer: n = 4

Step-by-step explanation:

The given expression is

2n+4=12

We want to solve for n. The first step is to make 2n stand alone on the left hand side of the equation. This is achieved by subtracting 4 from the left hand side and the right hand side of the equation. It becomes

2n + 4 - 4=12 - 4

2n = 8

The next step is to divide the left hand side and the right hand side of the equation by 2. It becomes

2n/2 = 8/2

n = 4
