Suppose that the functions h and g are defined as follows.
h(x)=x+6g(x)=(x4)(x2)
(a) Find (hg)(5).
(b) Find all values that are NOT in the domain of hg If there is more than one value, separate them with commas.

Answer

Final Answer: (b) Value(s) that are NOT in the domain of hg : 2,4

Steps

Step 1 :For part (a), we need to find the value of (hg)(5). This means we need to substitute x=5 into the function h(x)g(x).

Step 2 :For part (b), the values that are not in the domain of hg are the values of x for which g(x)=0, because division by zero is undefined in mathematics. So we need to solve the equation g(x)=0 to find these values.

Step 3 :Final Answer: (a) (hg)(5)=0.5

Step 4 :Final Answer: (b) Value(s) that are NOT in the domain of hg : 2,4
