Question

Hey ,
how to proove that "sin(x^3 +7x +1) "is continuous

Answer 1

Have you seen that if f and g are continuous so fog is continuous too?

Answer 2

ok so if we we treat sin(x) as f i.e continuous and g as (x^3 +7x +1) i.e also continuous so we can say that f(g(x)) is also continuous
is that correct ?

Answer 3

Yes

Answer 4

thank u :)

Answer 5
