SOLUTION: Find the vertex, x-intercept(s), and y-intercept of the parabola given by y=7x^2+21x-378. If the parabola does not have any x-intercepts, enter NONE for both coordinates of both in

Question 362085: Find the vertex, x-intercept(s), and y-intercept of the parabola given by y=7x^2+21x-378. If the parabola does not have any x-intercepts, enter NONE for both coordinates of both intercepts. If it has exactly one x-intercept, enter it as the first intercept and enter NONE for both coordinates of the second intercept. If it has two x-intercepts list them in increasing order.
