If f(x) = 2x and g(x) X
what is the domain of (fºg)(x)?
O x20
O all real numbers except x = 0
O xSO
O all real numbers

Domain is

All real number except at x=0

Step-by-step explanation:

We are given

Firstly, we will find (fog)(x)

now, we can plug back g(x)

Domain:

we know that domain is all possible values of x for which any function is defined

and we know that denominator of any function can not be zero

so, we set denominator =0

so, function will be defined for all values of x except at x=0

So, domain will be

All real number except at x=0

Hope this helps!

this doesn't make sense lol
