Q. What is the focus of the parabola y=4x2y = -4x^2?\newlineSimplify any fractions.\newline(______,______)
  1. Identify Parabola Type: y=4x2y = -4x^2 is a vertical parabola, so we use the formula y=a(xh)2+ky = a(x - h)^2 + k to find the focus.
  2. Find Parameters: Identify aa, hh, and kk. Here, a=4a = -4, h=0h = 0, and k=0k = 0.
  3. Calculate pp: Find the value of pp using p=14ap = \frac{1}{4a}. So, p=14(4)=116=116p = \frac{1}{4(-4)} = \frac{1}{-16} = -\frac{1}{16}.
  4. Determine Focus: The focus of a vertical parabola is (h,k+p)(h, k + p). So, the focus is (0,0+(116))(0, 0 + (-\frac{1}{16})).
  5. Final Result: Therefore, the focus is (0, - rac{1}{16}).
