Answer 17

first put -3 in place of x in function r(x)

Answer 18

the value you get from this, you put in place of x in q(x)

Answer 19

working :
\(=q[(r(-3)]\)
\(=q[-2(\color{red}{-3})^2+2)]\)
\(=q[-2(9)+2]\)
\(=q(-18+2)\)
\(=q(-16)\)
\(=2(\color{blue}{-16})-1\)
\(=-32-1\)
\(=?\)

solve it! @Hayhayz

Answer 21

Hayzio just for the future, when you have a question like this where it combines q(x) and r(x), you just combine the functions. The X was replaced by -3 in r(x) and q(x) so in the functions you simply replace those X variables with -3. Ez Pz
