    @tylertriebs You can use -b/2a to find the x coordinate of the vertex.

    |dw:1338548813555:dw| Put these values in formula -b/2a to get x coordiante .

    it means it is not your answer because vertex is (0,-5) take another equation in the same way and solve when value of x comes 0 then you will get your answer.
