Graphing Quadratic quiz

Which equation below is a quadratic?

• y=9x+5
• y=3x²-6
• y=5x³+6
• x=3^x

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
