Answer 2

It had better be "x = something."

Answer 3

"something" had better be > 0.

Answer 4

Imagine your curve was extended.
Now you need to find a point where a line can be drawn so there are two halves which reflect each other.

Answer 5

it would be 3?

Answer 6

yes :) but is it y = 3 or x = 3?
Imagine the line is drawn straight down.
Does it cut the curve on the x- axis or y - axis?

Answer 7

y=3?
