 Question 478792: 1.The vertex is(4,-7),and the parabola opens upward.Determine the number of x-intercepts. 2.The vertex is(-5,4),and the parabola opens downward.Determine tne number of x-intercepts. 3.The vertex is(2,0).Determine the number of x-intercepts. 4.The vertex is(4,2),and the y-intercepts is(0,5).Determine the number of x-intercepts. 5.The vertex is(-2,-5),and the parabola opens downward.Determine the number of x-intercepts.Answer by stanbon(60776)   (Show Source): You can put this solution on YOUR website!1.The vertex is(4,-7),and the parabola opens upward.Determine the number of x-intercepts. Vertex is below the x-axis and parabola opens up. 2 x-intercepts -------------------- 2.The vertex is(-5,4),and the parabola opens downward.Determine tne number of x-intercepts. Vertex: above x-axis Opens down: 2 x-int ==================== 3.The vertex is(2,0).Determine the number of x-intercepts. Vertex on x-axis: x-int: 1 ------------------ 4.The vertex is (4,2),and the y-intercepts is(0,5).Determine the number of x-intercepts. Low point at y = 2 Since y-int at y = 5, parabola opens up. x-int: none ------------------------ 5.The vertex is(-2,-5),and the parabola opens downward.Determine the number Hight point at y = -5 Opens down x-int: none ==================== cheers, Stan H.
