What is the minimum value of y = 3x2 + 12x − 4,

-16

Step-by-step explanation:

The minimum value is at the vertex

The x coordinate of the vertex = -b/2a

X = - 12/6 = - 2

Substituting the value of x in the equation

Y=3(-2)²+12(-2)-4

Y=3(4)-24-4

Y=12-24-4

Y=-16

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

i think the answer is b
