The graph of the piecewise function f(x) is shown. On a coordinate plane, a piecewise function has 2 lines that connect. The first line is horizontal to the y-axis at y = 4 and goes to (0, 4). The second line goes from (0, 4) through (4, 0).

What is the range of f(x)?

{f(x)| –∞ {f(x)| –∞ {f(x)|4 {f(x)|0≤f(x)<∞}
