Select all the correct answers. Which functions are correctly graphed? The Piecewise function graph shows a line that starts at (0, 2) and passes through (minus 2, 0). And a curve starts at the point (0, 1) and passes through (1, 2), and (2, 4). The equation f of x is equal to x plus 2, where the x is less than The graph shows the piecewise function, the line intersecting at the point (0, minus 2). The curve starts at the point (0, 0) and extends upwards. The equation f of x equals x minus 2 (minus infinity less than x less than 0) and 3 power x minus 1 A graph shows a parabola with a vertex of (0, 3). Another horizontal line starts from (minus1, minus 1) and passes to the left side. The function f of x is equal to minus 1 (infinity less than x less than 1) and f of x is equal to 3x square plus 3 The graph shows a parabola starts at (minus 2, 5) and vertex at (0, 1). And horizontal line start at (minus 2, 3) and passes to the left side. The equation of f of x equals
