Answer 2

just something to go off of

Answer 3

Assuming that the sign * is for (of) not multiplication, you can follow this:

\[p(x)=x-2\]\[p(2)=2-2\]\[p(2)=0\]
\[q(x)=x ^{2}+2\]\[q(2)=2 ^{2}+2\]\[q(2)=4+2\]\[q(2)=6\]
So,
(p*q)(2)= p(q(2))= 6-2=4
(q*p)(2)= q(p(2))= 0^2+2=2.

If the sign * is multiplication then.
(p*q)(2)= (0)(6)=0
(q*p)(2)=(6)(0)=0

Hope this helps.

Answer 4

the * is for multiplication!
