Question

Dada a função do 1 grau f (x) =(1-5x). Determinar a) f (0) b) f (-1) c) f (1/5) d) f (-1/5)

Answer 1

f(x) = (1 - 5x)

f(0) = (1 - 5*0) = (1 - 0) → f(0) = 1

f(-1) = (1 - 5(-1) ) = (1 +5) → f(-1) = 6

f(1/5) = (1 - 5(1/5) ) = (1 - 1) → f(1/5) = 0

f(-1/5) = (1 - 5(-1/5) ) = (1 + 1) → f(-1/5) = 2
