Answer:
They are similar by a factor of 14
Step-by-step explanation:
From the general equation of a parabola opening up (since the directrix is on the y axis and the focus is upwards this line) the focus coordinates are:
So h=0 and k+p=2, for the directrix:
solving k and p from the two equations above:
So for Parabola 1 the equation would be:
For Parabola 2 the general equation is:
here h=0, k=0, p=3/2 so focus is (0,3/2), directix is y=-3/2, they have the same orientation.
they are not congruent. For them to be similar it must comply:
replacing and solving for k:
They are similar by a factor of 14
