The solutions of x2 - 2x - 1 = 0 are the points of intersection of two graphs. if one of the graphs is y = 2 + x - x2, find the second graph
A
y = 1 - x
B
y = 1 + x
C
y = x - 1
D
y = 3x + 3
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
The second graph is
\((x^{2} - 2x - 1) + (2 + x - x^{2})\)
= \(1 - x\)
