Which equation represents a graph with a vertex at open paren negative 3 comma 2 close paren ?

For a quadratic y = ax² + bx + c, the vertex’s x-coordinate is −b/(2a). In choice B, a = 4 and b = 24, so the x-coordinate is −24/8 = −3. Substituting x = −3 gives y = 4(9) + 24(−3) + 38 = 2, so choice B has vertex (−3, 2).
