Since the directrix is vertical, use the equation of a parabola that opens up or down. ( ((x-h))^2=4p(y-k)) Find the vertex. ( (2,-1/2)) Find the distance from the focus to the vertex. ( p=3/2) Substitute in the known values for the variables into the equation(...
Thus, the directrix for our parabola is:Directrix=y=4 Step 5: Find the axis of the parabolaThe axis of the parabola is the line that runs vertically through the vertex and focus. For this parabola, the axis is the y-axis:Axis=x=0(or the y-axis) Step 6: Find the tangent at the...
