We can re-write the equation √(1-x) - 2y = 2 → - 2y = 2 - √(1-x)
→ 2y = - 2 + √(1-x) → and y = [ - 2 + √(1+x)]/2
Tis function "exists" as long as the radical is > or = to zero:
1+x > or = 0 → x>-1
{x ∈ R for x> =0}
Answer:
is this the question? or just a statement. Can you ask the question clearly?
Simply divide by 30 or 45 to see :)
