Question

Determine o valor númerícone da função afim; 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

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

f(1) = - 3 + 4

f(1) = 1

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

f(1/3) = - 1 + 4

f(1/3) = 3

c) f(0) = - 3(0) + 4

f(0) = 0 + 4

f(0) = 4

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

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

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