Question

Determine o valor da função afim f(x) = -3+4 para :
X=0,333 . Me ajudem pfv

Answer 1

$f(x)=-3x+4\\\\Para:\ x=0{,}333...\ \Rightarrow x=\dfrac{1}{3},\ t\^em{-}se:\\\\\\f\left(\dfrac{1}{3}\right)=-3\left(\dfrac{1}{3}\right)+4\\\\\\f\left(\dfrac{1}{3}\right)=\dfrac{-3}{3}+4\\\\\\f\left(\dfrac{1}{3}\right)=-1+4\\\\\\\boxed{f\left(\dfrac{1}{3}\right)=3}$


Caso seja: f(x) = -3 + 4x, temos:

f(1/3) = -3 + 4(1/3)

f(1/3) = -3 + 4/3

f(1/3) = -9/3 + 4/3

f(1/3) = -5/3
