    Couldn’t remotely comprehend the question before this video!!! My main teacher has gotten sick for 2 months now and our relief teacher did not cover this topic at all, but still expects us to know what to do… Thank you so much again!!!

    Was it given to you in the form of an equation? y = -x^2 - 4x - 5 ? This graph opens downward. Note that - (5)^2 = - 25 and - (-5)^2 = - 25

    son of a gun I thought the a Value had to be positive, so I divided the whole equation by -1. Got the same numbers for vortex, just wrong signs. (I only watched as far as figuring the vortex.) edit I fully watched, and yeah the step I took that messed me up I would only take if completing the square to solve for the x values. Cool video and love the bow tie. (reminds me of my dad he always wore one and was a great man)
