Question

determinar o valor da função f(x)= -3x+4 para
a) x= 1
b) x= 1÷3
c) x= 0
d) x= k+1

Answer 1

f(x)= -3x+4 para

a) x= 1 ==> f(1) = -3(1)+4==> - 3+4 ==> 1
================================================= 
b) x= 1÷3 ==> f(1/3) = -3(1/3)+4==> - 1+4 ==> 3
=================================================
c) x= 0 ==> f(0) = -3(0)+4==> 0+4 ==> 4
===================================================
d) x= k+1==> f(k+1) = -3(k+1)+4==> - 3k-3+4 ==> -3k+1====================================================
