Answer:
(0,5)
Explanation:
(1) y = -x² + 5
(2) y = x² + 5
2y =10 Added (1) and (2)
(3) y = 5 Divided each side by 2
5 = x² + 5 Substituted (3)into (2)
0 = x² Subtracted 5 from each side
x = 0 Took the square root of each side
The only ordered pair that represents a solution to both functions is (0, 5).
The graph of the second function is an upward-opening parabola (y = x²) translated up five units.
The graph of the first function is a downward-opening parabola (y = -x²) translated up five units.
The two graphs meet at their common vertex, (0, 5).
