Question

6)dadas as funções abaixo, determine o valor do coeficiente angular e do coeficiente linear:
a)f (x)=2×+3 b)f (x)=x+6 c)f (x)=-4×-3 d)f (x)=x+5

e)f (x)=-x+1 f)f (x)2x

Answer 1

$f(x)=ax+b$

O número que acompanha o $x$ é o coeficiente angular, o que fica sozinho é o coeficiente linear.

a) $f(x)=2x+3$
$a=2~~~~~~b=3$
$\text{coeficiente}~\text{angular}=2$
$\text{coeficiente}~\text{linear}=3$

b) $f(x)=x+6$
$a=1~~~~~~b=6$
$\text{coeficiente}~\text{angular}=1$
$\text{coeficiente}~\text{linear}=6$

c) $f(x)=-4x-3$
$a=-4~~~~~~b=-3$
$\text{coeficiente}~\text{angular}=-4$
$\text{coeficiente}~\text{linear}=-3$

d) $f(x)=x+5$
$a=1~~~~~~b=5$
$\text{coeficiente}~\text{angular}=1$
$\text{coeficiente}~\text{linear}=5$

e) $f(x)=-x+1$
$a=-1~~~~~~b=1$
$\text{coeficiente}~\text{angular}=-1$
$\text{coeficiente}~\text{linear}=1$

f) $f(x)=2x$
$a=2~~~~~~b=0$
$\text{coeficiente}~\text{angular}=2$
$\text{coeficiente}~\text{linear}=0$
