Question

Determine o valor da função afim f(X)=-3x+4 para:
x=1
x=1/3
x=0
x=k+1

Answer 1

f(1)= - 3 . 1 + 4
= -3 + 4
= 1
f(1/3)=-3 . 1/3 + 4
= -3/3 + 4
= -1 + 4
= 3
f(0)= -3 . 0 + 4
= 0 + 4
= 4
f(k + 1) = -3 .(k+1) + 4
= -3k - 3 + 4
-3k - 3 + 4 =0
-3k = 3 - 4
-3k = -1
-3k= -1 .(-1)
3k = 1
k= 1/3 ou k= 0,333...
