The equation for a parabola with directrix y = –p and focus (0, p)
The distance between vertex and directrix is P
Also the distance between vertex and focus is also P
Focus (0,p) so focus lies on y axis
Directrix line is paralled to focus point
So Directex crosses the x axis .
Hence line of symmetry lies is the y-axis.
The graph is attached below.
Answer:
A. (14,20)
Step-by-step explanation:
The inverse relation is found by swapping x and y in the ordered pair.
When ...
14 = f^-1(20)
then ...
20 = f(14)
The corresponding ordered pair is (14, 20).
