Question

- f(x) = 4x + 5, and g(x) = 2x – 9 ind (fºg)(x)

Answer 1

$(fog)(x) = 8x-31$

Step-by-step explanation:

The given question is of composition. composition means that one function is put into another

Given

$f(x) = 4x+5\\and\\g(x) = 2x-9$

$(fog)(x)=f(g(x))\\so,\\(fog)(x)=4(g(x))+5\\=4(2x-9)+5\\=8x-36+5\\=8x-31$

So,

$(fog)(x) = 8x-31$
