Given the functions defined by h(x)=x2−3x and k(x)=(x−2)−−−−−−√ , find kh(x) and write the domain of kh in interval notation

Step-by-step explanation:

Given

Solving (a): k(h(x))

Replace x with h(x)

Substitute:

Solving (b): The domain

For the function to be defined, the expression in the root must be greater than or equal to 0; i.e.

Solve for x;

Using a calculator, we have:

and --- approximated

So, the domain is:

bull
