Question

Seja F (×) = 4 x - 2 e g (x) = x -2 ,calcule

a) f (g (x) )



b) g (f (x) )​

Answer 1

Resposta:

Explicação passo a passo:

$f(x)=4x-2$

$g(x)=x-2$

$a)$

$f(g(x))=4.g(x)-2$

$f(g(x))=4.(x-2)-2$

$f(g(x))=4x-8-2$

$f(g(x))=4x-10$

$b)$

$g(f(x))=f(x)-2$

$g(f(x))=(4x-2)-2$

$g(f(x))=4x-2-2$

$g(f(x))=4x-4$
