(click on the picture if you don't know what i am talking about)

is the answer I can also give you the graph to if you need it, but that's how you would graph it. : ) Let me know if you need the graph
Answer: Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Vertex: (3, -1)
Focus: (3, - 3/4)
Axis of Symmetry: x = 3
Directrix: y = - 5/4
Step-by-step explanation:
graph{3x/(x^2-1) [-18.02, 18.02, -9.01, 9.02]}
3,400 since 81,600÷24= 3,400.
Answer: a = c^(1/2) which is the first answer choice of the list
Work Shown:
a = b^(2/3) ... given equation
a = (c^(3/4))^(2/3) ... replace b with c^(3/4)
a = c^((3/4)*(2/3)) .... multiply exponents
a = c^(1/2) .... Simplify; note the 3's cancel, also 2/4 turns into 1/2
