Question

Please help with this!
List the coordinates of the vertex & list two other points on the parabola:
x=y^2-2

Answer 1

Put the equation in vertex form first

Answer 2

How do i do that?

Answer 3

Get variables on one side and constant on the other

Answer 4

then complete the square

Answer 5

I dont understand any of this. what square?

Answer 6

would the vertex be (0,-2) ?

Answer 7

ok.
x=y^2-2
so you can pick a point for x and solve for y
y=\[\sqrt{x+2}\]
this will give you a few points on the parabola

Answer 8

so if x=1, then y=root 3, etc.

Answer 9

would one of the points be (-1.5,0) ?

Answer 10

The x value of the vertex is -b/2a from the quadratic formula
then substitute to find the y value f(-b/2a)

Answer 11

if you put in -1.5 you get sqroot of .5 so no

Answer 12

well would the vertex be (-2,0) ?

Answer 13

yes

Answer 14

Ok, (:
now can you help me find two points?

Answer 15

yes. Pick two numbers for x; plug them in the equation and solve for y.
y=root(x+2)
