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 A, x = −24/(2·4) = −3, and substituting −3 gives y = 4(9) + 24(−3) + 38 = 2. So choice A, y = 4x² + 24x + 38, has the vertex (−3, 2).
