Question

Dada a função f(x) = 12x -30, determine:

a) f(1) =
b) f(-1) =
c) f(0) =
d) f (5/3 ) =

Answer 1

Resposta:

a) -18     b) -42     c) -30    d) -10

Explicação passo-a-passo:

f(1) = 12.1 -30=> f(1) = 12 -30 => f(1) = -30

f(-1) = 12.(-1) -30=> f(1) = -12 -30 => f(1) = -42

f(0) = 12.0 -30=> f(1) = 0 -30 => f(1) = -30

$f(\frac{5}{3} )= \frac{12}{1} (\frac{5}{3} ) -30 => \frac{60}{3} \frac{}{} -30 +=> 20 \frac{}{} -30 => -10$
