The vertex for of the equation of a parabola is x = ( y - 4 )2 + 27 what is the standard form
Andru [333]
Important:  indicate exponentiation with " ^ "

Thus, x = ( y - 4 )2 + 27 becomes     <span>x = ( y - 4 )^2 + 27

This can be re-written as x = y^2 - 8y + 16 + 27, or x = ay^2 - 8y + 43.  This is the equation of the parabola in standard form   x = ay^2 + by + c.</span>
