If f(x) = 2x and g(x)=1/x, what is the domain of (fog)(x) x> _0 all real numbers except x=0 x< _0 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

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
