Minimum Maximum Domain and Range of Quadratic Functions

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

Using the graph of the quadratic function, identify the domain.

• y > -6

• -2 < x < 10

• -∞ < x < ∞

• y < -6
