A parabola in standard form y = ax² + bx + c is upside-down when a is:

• negative
• positive
• 0
• infinite

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