Question

Write the function whose graph is the graph of y=l x l but is shifted up 9 units.

Answer 1

The function is y = IxI + 9

Step-by-step explanation:

Let us revise the translation of a function

• If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)  
• If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)  
• If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k  
• If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k  

∵ y = IxI

∵ The graph of the function is shifted 9 units up

- That means the graph of the function is translated 9 units, up

∵ The equation of the function f(x) whose graph shifted k units

   up is f(x) + k

∵ k = 9

∴ The equation of the function is y = IxI + 9

The function is y = IxI + 9
