o a. the equation has a maximum value with a y-coordinate of -27.
b.
the equation has a maximum value with a y-coordinate of -21.
0
c.
the equation has a minimum value with a y-coordinate of -21.
0
d.
the equation has a minimum value with a y-coordinate of -27.

Option B.  The equation has a maximum value with a y-coordinate of -21.

Step-by-step explanation:

The correct quadratic equation is

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex represent a maximum

Convert to vertex form

Factor -3

Complete the square

Rewrite as perfect squares

The vertex is the point (2,-21)

therefore

The equation has a maximum value with a y-coordinate of -21

i think it would be c
