What is 4p in parabola

What is 4p in parabola- The vertex is (2,3) The focus is (5,3) The diretrix is x=1 Let's put y on one side of the equation and x on the other y^26y=12x33 We complete the square for the left side of the equation y^26y99=12x33 (y3)^29=12x33 (y3)^2=12x24 (y3)^2=12(x2) Since this is in the form of (yk)^2=4p(xh), we know this is a horizontal parabola Now, we can figure out that h=2, k Step 1 use the (known) coordinates of the vertex, (h,k), to write the parabola's equation in the form y=a (x−h)2k Step 2 find the value of the coefficient a by substituting the coordinates of point P into the equation written in step 1 and solving for a
