Does the following quadratic equation have a maximum or minimum value? How can you tell?

y=-x²+2x-3

• Maximum value, because the a value is negative

• Maximum value, because the b value is positive

• Maximum value, because the a value is positive

• Minimum value, because the c value is negative
