To find the range of the function f(x) = x² + 2 for any domain value, we simply substitute the domain value into the function and solve for the corresponding range value.
Let's substitute the domain value 'y = 2':
2 = x² + 2
Subtract 2 from both sides:
0 = x²
This implies that x = 0.
Therefore, for the domain value y = 2, the corresponding range value is x = 0.
Therefore, the correct answer is y = 2.
