What is the vertex of the function f(x) = x2 + 12x?

(–6, –36)

(–6, 0)

(6, 0)

(6, –36)

Option A is correct

(–6, –36)

Step-by-step explanation:

A quadratic equation is in the form of  ,....[1] then the axis of symmetry is given by:

Vertex of the function is given by:

As per the statement:

Given the function:

          ....[2]

Compare this with equation [1] we have;

a = 1 and b = 12

then;

⇒

⇒x = -6

Substitute the value of x in [2] we have;

⇒f(-6) = -36

⇒Vertex = (-6, -36)

Therefore, the vertex of the function f(x) is, (–6, –36)

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
