CCSS.HSF.IF.B.5

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 domain of the graph?

• All real numbers

• To infinity and beyond

• y ≥ 0

• x ≥ 0
