[tex](fog)(x) = 8x-31[/tex]
Step-by-step explanation:
The given question is of composition. composition means that one function is put into another
Given
[tex]f(x) = 4x+5\\and\\g(x) = 2x-9[/tex]
[tex](fog)(x)=f(g(x))\\so,\\(fog)(x)=4(g(x))+5\\=4(2x-9)+5\\=8x-36+5\\=8x-31[/tex]
So,
[tex](fog)(x) = 8x-31[/tex]
