Question

Quais são os valores de a e de b na equação do primeiro grau? f (x) = 3x + 1 
com cálculo​

Answer 1

Resposta:

F(x) = ax + B ou seja o valor de A e igual a 3 e B = 1

Explicação passo a passo:

Nao precisa de calculo.

Espero ajudar

Answer 2

$\text{\pink{ \Longrightarrow }~\Large\orange{ \sf (x, y) }}$ sendo as coordenadas dos pontos que pertencem à reta descrita pela função;

$\text{\pink{ \Longrightarrow }~\Large\orange{ \sf a }}$ sendo o coeficiente angular da reta: a tangente do ângulo formado entre a reta e o eixo das abscissas (Δy / Δx);

$\text{\pink{ \Longrightarrow }~\Large\orange{ \sf b }}$ sendo o coeficiente linear da reta: o valor de y para quando a reta intercepta o eixo das ordenadas (x = 0).
