Answer:
[tex](f\circ \: g)(x) = {3x}^{2} - 6[/tex]
Step-by-step explanation:
f(x) = x - 5
g(x) = 3x² - 1
To find (fºg)(x) substitute g(x) into f(x) that's for every x in f (x) replace it with g (x)
That's
[tex](f\circ \: g)(x) = 3 {x}^{2} -1 - 5 [/tex]
We have the final answer as
[tex](f\circ \: g)(x) = {3x}^{2} - 6[/tex]
