Point A belongs to the graph of the function y (x) = -x² + 5 if its coordinates satisfy the function expression.
Substituting the coordinates of point A (x = 0; y = 5) into the function expression, we get:
5 = y (0) = -0² + 5 = 0 + 5 = 5. Correct. Thus, point A belongs to the graph of the specified function.
The answer is yes.
