Question

For f(x)=1/(x-5) and g(x)=x^2+2, find: (fog)(x) and (gof)(6)

Answer 1

(fog)=f(g(x))..
sbstitute g(x)value in f(x)...u will get (fog)

(gof)=g(f(x))..
substitute f(x) in g(x) ....then to the solution substitute x=6 ... u will get the ans.....

Answer 2

so (fog)(x) is?

Answer 3

1/(x^2 - 3)?

Answer 4

wat's ur confusion ....
