Focus of the parabola is (-5,5) and directrix is y = -1.
Let's assume a point (x,y) on parabola.
According to definition of parabola, the distance between point (x,y) and focus (-5,5) would be same as the distance between the point (x,y) and directrix y = -1.

Hence, option D is correct, i.e. f(x) = one twelfth (x + 5)2 + 2.
Difference would be that is a diameter is double a radius and a radius is half of a diameter.
A similarity would be that they would are within a circle and touch the center of circle

In order to form a triangle, the sum of two sides must be GREATER than the third side.
a + b > c & a + c > b & b + c > a
5 + 2 > 4 & 5 + 4 > 2 & 4 + 2 > 6
True True True
The sides 5, 2, 4 satisfy the rules for forming a triangle.
