I have already solved for the vertex, and I am trying to figure out the vertex form of an equation, how do I figure out another y intercept so that I can finish the equation y = a(x-2)^2-63 and solve for "a"? Please explain step-by-step. Will give brainliest. Thanks!

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
