The piecewise function f(x) has opposite expressions. f(x) = startlayout enlarged left-brace 1st row 1st column 2 x minus 1, 2nd column x less-than 0 2nd row 1st column 0, 2nd column x = 0 3rd row 1st column negative 2 x + 1, 2nd column x greater-than 0 which is the graph of f(x)? on a coordinate plane, a piecewise function has 2 lines. the first line goes through (negative 3, 4) and goes down to a closed circle at (negative 1, 0). the second line has a closed circle at (1, 0) and goes up through (3, 4). on a coordinate plane, a piecewise function has 2 lines. the first line goes up through (negative 3, negative 4) to a closed circle at (0, 2). the second line has a closed circle at (0, 2) and goes down through (3, negative 4). on a coordinate plane, a piecewise function has 2 lines. the first line goes up from (negative 2, negative 5) to a closed circle at (0, negative 1). the second line has a closed circle at (0, 1) and goes down through (2, negative 3). on a coordinate plane, a piecewise function has 2 lines. the first line goes down through (negative 1, 3) to a closed circle at (0, 1). the second line has a closed circle at (0, negative 1) and goes up through (2, 3).
