Answer 1

Answer: (qor)(x)=24x+3

(roq)(x)=24x+18

Explanation:

q(x) = 4x + 3

r(x) = 6x

(qor)(x)=

q(r(x))=

q(6x)=

4(6x)+3=24x+3

(roq)(x)=

r(4x+3)=

6(4x+3)=24x+18

Answer 2

`(q \circ r)(x)=q(r(x)) \\ \\ =q(6x) \\ \\ =4(6x)+3 \\ \\ =24x+3 \\ \\ \\ \\ (r \circ q)(x)=r(q(x)) \\ \\ =r(4x+3) \\ \\ =6(4x+3) \\ \\ =24x+18`
