Estou a 1 mês postando esses mesmos exercícios aqui no brainly, estou desesperada. Alguém me ajudaaaaaaaaaa?????? Por favor Exer

cícios 1) Nas funções abaixo, identificar se é crescente ou decrescente, obter a raíz, obter as coordenadas e montar o gráfico. a) y = 2x + 6 raíz => ___ Coordenadas ( , ) ; ( , ) Função ( ) crescente ( ) decrescente b) y = -3x - 6 raíz => ___ Coordenadas ( , ) ; ( , ) Função ( ) crescente ( ) decrescente c) y = 4x - 8 raíz => ___ Coordenadas ( , ) ; ( , ) Função ( ) crescente ( ) decrescente d) y = - 2x - 4 raíz => ___ Coordenadas ( , ) ; ( , ) Função ( ) crescente ( ) decrescente e) f(x) = x + 5 raíz => ___ Coordenadas ( , ) ; ( , ) Função ( ) crescente ( ) decrescente f) f(x) =10x - 2 raíz => ___ Coordenadas ( , ) ; ( , ) Função ( ) crescente ( ) decrescente g) f(x) = -16x + 2 raíz => ___ Coordenadas ( , ) ; ( , ) Função ( ) crescente ( ) decrescente h) f(x) = 1/2x + 4 raíz => ___ Coordenadas ( , ) ; ( , ) Função ( ) crescente ( ) decrescente 2) Como a função de 1º grau é do tipo f(x)=ax +b, prove que a é a taxa de variação das funções abaixo Pode ser utilizada a 2ª fórmula. a) f(x) = √2 x + 4 b) g(x) = 1/4 + 1/2x 3) Para as funções abaixo, atribuir valores -1, 0 ,1 para x, calcular os valores para y e montar os dois gráficos em um mesmo plano (igual ao exemplo). a) f(x) = -2x + 3 b) g(x) = 5x + 1 4) Para as funções abaixo, construir o gráfico em um mesmo plano cartesiano, com apenas 3 pontos, para isso utilize ∆ e a fórmula do vértice. a) x² -3x+2 b) -x² +x +2 5) Para as funções abaixo analise a concavidade da parábola, encontre o ponto de máximo ou de mínimo e as raízes. a) x² + 4x b) -x² +4 6) Analise a taxa de crescimento das funções abaixo a) x² -4 b) -x² +4
