Question

Graph the function, with the focus and directrix shown on the graph, as well. Attachment

Answer 1

@julian25

Answer 2

(x-2)^2 =4*1y

Answer 3

the focus is 0,4?

Answer 4

close the problem here is that parabola is translate to the right 2 units because the factor (x-2)

Answer 5

so the focus is 0,2

Answer 6

no well if the equation where
x^2 = 4*1y the focus woulb be (0,4) like u say

Answer 7

wait the focus is in y=1

Answer 8

and the directirx would be -1

Answer 9

where do u got the 4

Answer 10

u say (0,4) but it is (0,1)

Answer 11

i got confused with the other way the one that you gave an example of

Answer 12

x^2 = 4*1y

Answer 13

for this equation
x^2 = 4*1
the focus is (0,1)

Answer 14

x^2 = 4*1y

Answer 15

ok and the directrix is -1 then, right?

Answer 16

and te graph is the one that i made

Answer 17

yes but we are working with this
(x-2)^2 =4*1y

Answer 18

so u must translate the focus to the right

Answer 19

ok i get it

Answer 20

really? so what is the focus?

Answer 21

0,1

Answer 22

x^2 = 4*1y for this is (0,1)

Answer 23

because you move to 2 to the right

Answer 24

for that one (x-2)^2 =4*1y u must move the graph 2 units to the right

Answer 25

right!

Answer 26

for the directrix would the line be vertical or horizontal?
