Explanation: The equation f(x) = -(x-6)^2 - 20 is the same as y = -1(x-6)^2 + (-20) It is in the form y = a(x-h)^2 + k The vertex is (h,k) In this case, h = 6 and k = -20 So that's why the vertex is (6,-20)
Some ordered pairs are:(10,5), (0,9), and (3,15) that make the equation true. Hope this helps!! ::)) Please rate as brainliest (if it helped at all)!! ::))
