Diketahui :

[tex]\bf{f\left(x\right)=5x+2}[/tex]

[tex]\bf{g\left(x\right)=2x^{2}-6x-8}[/tex]

Maka

[tex]\boxed{\bf{\left(f+g\right)\left(x\right)=2x^{2}-x-6}}[/tex]

[tex]\boxed{\bf{\left(f-g\right)\left(x\right)=-\left(2x^{2}-11x-10\right)}}[/tex]

[tex]\boxed{\bf{\left(f\times g\right)\left(x\right)=2\left(5x^{3}+2x^{2}-21x-28\right)}}[/tex]

[tex]\boxed{\bf{\left(f:g\right)\left(x\right)=\frac{\left(5x+2\right)}{\left(2x^{2}-6x-8\right)}}}[/tex]

[tex] \small\boxed{\boxed{\mathbf{B.\ \ Domain,\ Kodomain,\ dan\ Range}}}[/tex]

Suatu fungsi f memetakan A ke B (f : A → B) dan jika x ∈ A dan y ∈ B, maka f : x → y atau f(x) = y, sehingga :

[tex] \tiny\boxed{\begin{array}{c}\mathbf{1. \ domain\ (daerah\ asal)}\\\mathbf{\to himpunan\ semua\ anggota\ A\ dari\ pasangan\ terurut \ (x,y)}\\\\\mathbf{2.\ Kodomain\ \left(daerah\ kawan\right)}\\\mathbf{\to himpunan\ semua\ anggota\ himpunan\ B.}\\\\\mathbf{3.\ Range\ \left(daerah\ hasil\right)}\\\mathbf{\to himpunan\ semua\ anggota\ himpunan\ B\ dari\ pasangan\ terurut \ (x,y).}\end{array}}[/tex]

[tex] \boxed{\boxed{\mathbf{D,\ \ Fungsi\ Komposisi}}}[/tex]

[tex] \scriptsize\mathbf{1.\ Fungsi\ komposisi\ dapat\ ditulis\ sebagai\ :}\\\\\mathbf{\left(f \circ g\right)\left(x\right)=f\left(g\left(x\right)\right)\to komposisi\ g}\\\mathbf{\left(g \circ f\right)\left(x\right)=g\left(f\left(x\right)\right)\to komposisi\ f}[/tex]
