Compare the graph of the function with the graph of its parent function. y= |x +4 Oy=x+4 is f(x) = |x| shifted up 4 units. Oy = x + 4 is f(x) = |x| Oy = x + 4 is f(x) = |x| Oy = x + 4 Oy = x + 4 is f(x) = |x| is f(x) = |x| vertically stretched 4 fold. shifted to the left 4 units. horizontally stretched 4 fold. shifted to the right 4 units.
