Final answer:
The value of x + 3 - y² is -4.
Step-by-step explanation:
To find the value of x + 3 - y² when x = -3 and y = 2, we substitute these values into the expression. We have:
x + 3 - y² = -3 + 3 - (2)² = -3 + 3 - 4 = 0 - 4 = -4
Therefore, when x = -3 and y = 2, the value of x + 3 - y² is -4.
