Quadratic Relations

Consider the parabola of the form $y=ax^2+bx+c$`y`=`a``x`2+`b``x`+`c`, where $a\ne0$`a`≠0

Fill in the gaps to make the statement true.

The $x$`x`-coordinate of the vertex of the parabola occurs at $x=\editable{}$`x`=. The $y$`y`-coordinate of the vertex is found by substituting $x=\editable{}$`x`= into the parabola's equation and evaluating the function at this value of $x$`x`.
