How would I find the a for the equation y= a(x-h)^2+k. I'm looking at a graph, and I can solve for everything except for a. What is it supposed to be?

Answer 1

If you can see the vertex, fill in those values
e.g. if the vertex is (5,7)
your equation would be
y = a(x-5)^2 + 7

Now see if you can find another point given on your curve, and sub that point in for the x and y, leaving a as the unknown that you can solve for.

Answer 2

Thank you.

Answer 3

If you have a equation how do you transfer that into a table?
without using a graphing calculator?

Answer 4

how do you make a table out of an equation??
