Which statement is true about the extreme value of the given quadratic equation? y = -3x2 + 12x − 33

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

Step-by-step explanation:

Given

Required

The true statement about the extreme value

First, write out the leading coefficient

means that the function would be a downward parabola;

Downward parabola always have their vertex on top of the parabola and as such, the function has a maximum value.

The maximum value is:

Where:

So, we have:

Substitute in

Hence, the maximum is -21.

5x+10 is the correct one

hope this
