Question

determine o valor da funçao afim f(x) = -3x + 4 para:

a, x=1

b, x=1/3

c, x=0

x=k+1

Answer 1

Resposta:

a) x = 1

f(1) = -3 · 1 + 4

f(1) = -3 + 4

f(1) = 1

b) x = 1/3

f(1/3) = -3 · (1/3) + 4

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

f(1/3) = -1 + 4

f(1/3) = 3

c) x = 0

f(0) = -3 · 0 + 4

f(0) = 0 + 4

f(0) = 4

d) x = k + 1

f(k + 1) = -3 · (k + 1) + 4

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

f(k + 1) = -3k + 1
