Answer:

y = 3x

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition when x = 7, y = 21

k = \frac{y}{x} = \frac{21}{7} = 3

y = 3x ← equation of variation

Write a function g whose graph represents the indicated transformation of the graph of f F(x)=4-|x+1|
marshall27 [118]

The function g from the indicated transformation of the graph of f is g(x) = 4 - |x  - 2|

<h3>What is a function?</h3>

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The equation of the function f is given as :

F(x) = 4-|x+1|

Shifting of a graph is done by adding any arbitrary constant to the function in shifting.

For example, If shift up by 1 unit,  add 1 to the function

So the function g(x) is 3 units to the right of the function f(x)

⇒ g(x) = f(x - 3)

So, F(x - 3) = 4 - |x - 3+ 1|

Evaluate both equations,

⇒ F(x - 3) = 4 - |x  - 2|

⇒ g(x) = 4 - |x  - 2|

Hence, the function g from the indicated transformation of the graph of f is g(x) = 4 - |x - 2|
