1. Problem Description

The problem requires us to find the points of intersection of the two given curves: y=x2y = x^2 and y=x2+2y = -x^2 + 2.

2. Solution Steps

To find the points of intersection, we need to solve the system of equations:
y=x2y = x^2
y=x2+2y = -x^2 + 2
Since both equations are equal to yy, we can set them equal to each other:
x2=x2+2x^2 = -x^2 + 2
Add x2x^2 to both sides:
2x2=22x^2 = 2
Divide both sides by 2:
x2=1x^2 = 1
Take the square root of both sides:
x=±1x = \pm 1
Now we can find the corresponding yy values for each xx value using the equation y=x2y = x^2:
If x=1x = 1, then y=(1)2=1y = (1)^2 = 1.
If x=1x = -1, then y=(1)2=1y = (-1)^2 = 1.
Thus, the intersection points are (1,1)(1, 1) and (1,1)(-1, 1).

3. Final Answer

The points of intersection are (1,1)(1, 1) and (1,1)(-1, 1).
