Dik f(x) = 2xpangkat2+1 = g(x) x-1 tentukan fog(-1) dan gof(-1)

=F(g(-1)) =F(-1-1)
=2([tex] -2^{2} [/tex] )
=2(4)=8

g(f(-1))=g([tex] 2x^{2} [/tex] + 1)
=g(2([tex]-1^{2} [/tex]) +1)
=g(2(2))
=4-1
=3

=F(g(-1)) =F(-1-1)
=2(-2^{2}−2​2​​ )
=2(4)=8

g(f(-1))=g(2x^{2}2x​2​​ + 1)
=g(2(-1^{2}−1​2​​ ) +1)
=g(2(2))
=4-1
=3
Klo salah maaf yaa
