Question

dada a função f(x)=3x-2 calcule f(-3)​

Answer 1

Resposta:

f(x) = x² – 2

a)

f(–1) = (–1)² – 2

f(–1) = 1 – 2

f(–1) = –1

b)

f(1) = 1² – 2

f(1) = 1 – 2

f(1) = – 1

c)

f(0) = 0² – 2

f(0) = – 2

Answer 2

Resposta:

f(-3) = - 11

Explicação passo a passo:

f(x) = 3x - 2

f(-3) = 3(-3) - 2

f(-3) = - 9 -2

f(-3) = - 11
