Which is the graph of f(x) = (x + 3)(x – 2)? on a coordinate plane, a parabola opens up. it goes through (negative 3, 0), has a vertex at (negative 0.75, negative 6), and goes through (2, 0). on a coordinate plane, a parabola opens up. it goes through (negative 2, 0), has a vertex at (0.5, negative 6. 2), and goes through (3, 0). on a coordinate plane, a parabola opens down. it goes through (negative 3, 0), has a vertex at (negative 0.5, 6. 2), and goes through (2, 0). on a coordinate plane, a parabola opens down. it goes through (negative 2, 0), has a vertex at (0.5, 6. 2), and goes through (3, 0).
