Question 1

What are the focus and directrix of the parabola  x2 - 4x = 4y?
◦ focus (2, -1), directrix y = 1
◦ focus (2, 0), directrix y = -2
◦ focus (2, 1), directrix y = -1
◦ focus (2, 3), directrix y = -5
◦ focus (0, 0), directrix y =  -1

Question 2

Give the equation of the graph that results from the scaling the graph of  y = so that vertical distances are divided by 5 and the horizontal distances are multiplied by 3.
◦ 5y =
◦ 5y =
◦ y = 5
◦ 5y =
◦ y = 5
