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
