We have the following expression:
 (27a ^ 3-1) / (9a ^ 2-6a + 1)
 Rewriting we have:
 (27a ^ 3-1) / (9a ^ 2-6a + 1)
 (27a ^ 3-1) / ((3a-1) * (3a-1))
 We exclude the values that make the denominator zero:
 3a-1 = 0
 a = 1/3
 Answer:
 
a valid exclusion for the algebraic fraction is:
 
c. a ≠ 1/3

Answer:

The answer to your question is: third option is correct

Step-by-step explanation:

Data

F (5, -1)

directrix   y = 1

Then, after getting the graph, the vertix = (5, 0)

                                                        and p = 1

                 Formula

                              (x - h) ² = -4p(y - k)

                              (x - 5)² = -4(1)(y - 0)

                              (x - 5)² = -4y

                              y = (x - 5)² / -4
