Question

sendo f(x) =12-5x determine .
A)f(3)
b)f( 10)
c)(f-6)
d) f(0)​

Answer 1

Resposta:

A)

f(x) = 12 - 5x

$f(3) = 12 - 5(3) \\ \\ f(3) = 12 - 15 \\ \\ \blue{ f(3) = - 3}$

B)

$f(10) = 12 - 5(10) \\ \\ f(10) = 12 - 50 \\ \\ \blue{f(10) = - 38}$

C)

$f( - 6) = 12 - 5( - 6) \\ \\ f( - 6) = 12 + 30 \\ \\ \blue{ f( - 6) = 42}$

D)

$f(0) = 12 - 5(0) \\ \\ f(0) = 12 - 0 \\ \\ \blue{ f(0) = 12}$
