Which graph represents the piecewise-defined function f(x) = StartLayout enlarged left-brace 1st Row 1st column negative 1.5 x + 3.5, 2nd column x less-than 2 2nd row 1st column 4 + x, 2nd column x greater-than-or-equal-to 2 EndLayout? On a coordinate plane, a piecewise function has 2 lines. The first line has an open circle at (2, 0) and then goes up through (1, 2) with an arrow instead of an endpoint. The second line has a closed circle at (2, 6) and goes up through (3, 7) with an arrow instead of an endpoint.
