Horizontal axis means of form: (y-k)^2 = 4p(x-h) if the vertex is at the origin (h,k) = (0,0) y^2 = 4 p x 36 = 4 p (4) p = (9/4) so y^2 = 9 x

If (2f)(5) is supposed to mean 2 f(5), then the answer is 2 * (25 +1) = 52. Why did you bother to define g(x) if it isn't used in the question?

1) looks like you are dealing with the cubes so term(n) = n^3 2) did you notice that each term is one less than a perfect square? e.g. 3 = 2^2 - 1 --term(1) 8 = 3^2 -1 -- term(2) 15 = 4^2 -1 24 = 5^2 - 1 35 = 6^2 - 1 so term(n) = (n+1)^2 -1

the General term(r+1) = C(12,r)(x^2)^(12-r)(3^r) = C(12,r)(x^(24-2r)(3^r) so ax^8 = C(12,r)(x^(24-2r)(3^r) then 24-2r = 8 r = 8 It must be the 9th term and it must be C(12,8)x^8(3^8) = 495(6561)x^8 so a = 3247695
