The domain of both

f(x)=x−6
and

g(x)=x+6
is all real numbers. what is the domain of

h(x)=f(x)g(x)
?

The domain of function is set of all real numbers.

Domain: (-∞,∞)

Step-by-step explanation:

Given:

the domain of both the above functions is all real number.

To find domain of :

Substituting functions and to find

The product can be written as difference of squares.

∴

The degree of the function is 2 as the exponent of leading term is 2. Thus its a quadratic equation.

For any quadratic equation the domain is set of all real numbers.  

So Domain of is (-∞,∞)

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
