Answer:
F(1,5)
Step-by-step explanation:
This is a vertical parabola.
The vertex is at (1,4).
The directrix is y=3.
The distance from the vertex to the directrix is p=1
The focus is (1,4+p), which is (1,4+1)
Therefore the focus is (1,5)
3 and 1 half is also known as 3.5,
3.5 x 3.5 = 12.25
in fractions that is 12 and 1 quarter
In order to answer the question, it's absolutely essential to have
enough of a description of the object to know which of its parts
'X', 'Y', and 'Z' are, and what other parts it may have.
An ideal way to accomplish this would have been for you to include the
picture that accompanies the question, wherever you copied it from.
