Gavin graphs the parabola (x+1)²=-8(y+3)
How does he proceed?
Drag a value, coordinates, an equation, or a word to each box to correctly complete the statements.
Gavin identifies that the vertex of the parabola is ? The parabola opens
and the focus is ? units away from the vertex. The directrix
is ? units from the focus. The focus is the point ? The directrix ? of the equation is ?
Gavin plots the vertex and focus, and graphs the directrix as a dashed line. He then draws the parabola so that the focus sits inside the curve and the directrix does not intersect it.
