The answer is maximum.

Aliya Logan · Answer 2

maximum

Step-by-step explanation:

For a quadratic in standard form : y = ax² + bx + c : a ≠ o

We can determine if maximum or minimum by considering the sign of a

• If a > 0 then minimum

• If a < 0 then maximum

Here a = - 3 < 0

Hence y = - 3x² + 5 is maximum
