1) Construa o gráfico da função afim dada pela lei indicada : f(x): - x + 5,utilize valores de x= -1,0,1 2) Construa o gráfico das funções quadrática a seguir: f(x):(x+4)(x+4). Não se esqueça de fazer todas as etapas: verificar a concavidade, achar o eixo Oy(x=0), encontrar Bháskara , encontrar o Xy e Yv e fazer o gráfico no plano cartesiano.

sorry it's to hard I don't know the exact answer

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

the answer is d. (1.2, -4.7) on edgn

hope this !
