Does the following quadratic equation have a maximum or minimum value? How can you tell?
g(x) = x² + 2x - 3

• Minimum value, because the a value is positive
• Maximum value, because the b value is positive
• Maximum value, because the a value is positive
• Minimum value, because the c value is negative
