Use the normal skeleton egg spawn in the biome of snow and appears the Stray, use the zombie spawnegg in the desert biome and will appear Husk. There was supposed to be spawn eggs for them, but it seems they were removed either intentionally or by accident in the final release.
How Do You Find the Axis of Symmetry for a Quadratic Function? The axis of symmetry is the vertical line that goes through the vertex of a quadratic equation. There's even a formula to help find it! In this tutorial, you'll see how to find the axis of symmetry for a given quadratic equation.
The axis of symmetry is also defined by the following equation: x = - b /2 a. Remember, a quadratic function has the following form: y = ax 2 + bx + c. Follow 4 steps to use an equation to calculate the line of symmetry for y = x 2 + 2 x. 1  Identify a and b for y = 1 x 2 + 2 x. a = 1; b = 2. 2  Plug into the equation x = - b /2 a. 3  x = -2/(2*1). 4  Simplify. 5  x = -2/2. 6  The line of symmetry is x = -1.
