Identify the vertex for the graph of y = 3x2 + 12x + 5.

(2, 41)
(2, 35)
(−2, −31)
(−2, −7)

 The correct option is (D) (-2, -7).

Step-by-step explanation:  We are given to identify the vertex for the graph of the following function :

We know that

the vertex of the graph of the function is given by

From equation (i), we have

Therefore, the vertex of the graph of function (i) will be

Thus, (D) is the correct option.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
