Question

dada as funções f (x)=x+10 e g(x)=2x-3 determinemine a) f(g (3)) b)gof

Answer 1

f ( x ) = x + 10
f(g(x)) = g(x) +10
f(g(x)) = 2x-3 +10
f(g((x)) =2x+7
f(g(3)) = 2(3) +7 = 6+ 7 = 13 ✓

g ( x ) = 2x -3
gof(x) = 2(f)-3=2(x+10)-3=2x+17

Answer 2

Resposta:

f(x)=x+10  g(x)=2x-3

a)f(g(3))=f(2x-3)=2x-3+10

f(g(3))=2x+7=2*3+7=6+7=13

b) g(f(x))=g(x+10)=2(x+10)-3

g(f(x))= 2x+20-3=2x+17
