1)indique se as funçoes abaixo possuem ponto maximo ou ponto minimo

a) y= -3x2+5

b) y=x2 - 6x +5

c) y=x2

d) y=9x + x2 +7

2) as coordenadas do vertice v da parabola que representa a funçao f(x)=x2 - 2x -3 sao:

a) v=(1,-4)

b)v=(2,4)

c)v=(-1,4)

d)y=9x+x2+7

3)calcule o valor do delta de cada funçao quadratica e depois responda:

a) y= x2+7x+10

b) y=x2+7x+20

c)y=x2 +6x +9

qual das funcoes quadraticas acima

a) nao admite raizes reais?

b) admite 2 raizes reais e iguais?

c) possui 2 raizes reais e destintas?

7) determine os zeros da funçao y=+x2+4x-5: [tex][/tex]

yes yes yes yes yes yes yes yes yes

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

∠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.

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )
