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

What is the vertex?

• (2, 4)
• (3, -1)
• (0, 8)
• (4, 2)

• The function is Odd
• The function is Even
• The function has 5 real zeros
• The function is Positive
