Question

sendo g (x)=2x+1 e f(x)=x+3 determine b) gog(0)

Answer 1

g(x)=2x+1

gog(x)=2*(2x+1)+1
gog(x)=4x+2+1
gog(x)=4x+3

gog(0)=4*0+3
gog(0)=3

Espero que tenha entendido!

Answer 2

g(g(0)) = ?

g(0) = 2x + 1
g(0) = 2.0 + 1
g(0) = 1

g(g(0)) = ?
g(1) = 2x + 1
g(1) = 2.1 + 1
g(1) = 2 + 1
g(1) = 3
