Question

me ajudem nessa pfv!

Exercício: 1) Dada a função f(x) = 3x - 7, determine o valor de: a) f(0) b) f(5) c) f(-3) d) f(-1) e) f(3)​

Answer 1

Resposta ↓

f(0) = - 7

f(5) = 8

f(-3) = - 16

f(-1) = - 10

f(3) = 2

Explicação passo a passo:

⇒ Para resolvermos, substituímos x por cada valor pedido em cada função:

=====================================================

Função => ${\boxed{\sf f(x) = 3x - 7}$

✍ Cálculo:

$a)\ f(0) = 3.0 - 7\\\\\\a)\ f(0) = 0 - 7\\\\\\a)\ f(0) = - 7$

=====================================================

$b)\ f(5) = 3.5 - 7\\\\\\b)\ f(5) = 15 - 7\\\\\\b)\ f(5) = 8$

=====================================================

$c)\ f(-3) = 3.(-3) - 7\\\\\\c)\ f(-3) = - 9 - 7\\\\\\c)\ f(-3) = - 16$

=====================================================

$d)\ f(-1) = 3.(-1) - 7\\\\\\d)\ f(-1) = - 3 - 7\\\\\\d)\ f(-1) = - 10$

=====================================================

$f(3) = 3.3 - 7\\\\\\f(3) = 9 - 7\\\\\\f(3) = 2$

f(0) = - 7

f(5) = 8

f(-3) = - 16

f(-1) = - 10

f(3) = 2

Espero ter ajudado :)
