Question

f(x)1-5x determinar f(-1/5)

Answer 1

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

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

f(-1/5) = 2

Answer 2

F(x) = 1 - 5x

F(- 1/5)

$\mathtt{F(-\frac{1}{5}) = 1 - 5~.~-\frac{1}{5}} \\ \\ \mathtt{F(-\frac{1}{5}) = 1 +\frac{5}{5}} \\ \\ \mathtt{F(-\frac{1}{5}) = 1 +1} \\ \\ \mathtt{F(-\frac{1}{5}) = 2} \\ \\ \\ \boxed{\boxed{\mathtt{Resposta: F(-frac{1}{5}) = 2}}}$
