Question

What is an equation of a parabola with vertex at the origin and focus (-6,0)?

Answer 1

@vocaloid do you know how to do this kind of problem?

Answer 2

the focus is on the x-axis so the graph must open either left or right

Answer 3

so, would the equation look like

y = x^2
or
x = y^2?

Answer 4

the first one?

Answer 5

you sure

Answer 6

use the draw button to show me what the graph of y = x^2 looks like

Answer 7

i dont know what it looks like im just guessing because i dont know how to do this problem

Answer 8

ok

Answer 9

remember:

y = x^2 is an upward/downward parabola
x = y^2 is a parabola that opens left or right

Answer 10

so its x=y^2

Answer 11

good

the parabola in the problem opens left

Answer 12

oh i kind of see that part now. because x goes horizontal

Answer 13

so the number in front of y^2 is negative

Answer 14

so it must be the last option

Answer 15

are you sure
