Question

Dada a função f(x) = 3x+2, calcule:

f(2/3)

f(1/5)​

Answer 1

Resposta:

Explicação passo-a-passo:

f(x) = 3x+2

f(2/3)  = 3(2/3) + 2 => $f(\frac{2}{3}) = 3(\frac{2}{3}) + 2 => f(\frac{2}{3}) = \frac{6}{3} + 2 => f(\frac{2}{3}) = 2 + 2 => f(\frac{2}{3}) = 4$

f(1/5)​= $f(\frac{1}{5}) = 3(\frac{1}{5}) + 2 => f(\frac{1}{5}) = \frac{3}{5} + 2 => f(\frac{1}{5}) = \frac{3.1 + 2.5}{5} => f(\frac{1}{5}) = \frac{3 + 10}{5} => f(\frac{1}{5}) = \frac{13}{5}$
