Question

Suppose that the functions and are defined as follows.

find (q ° r) and (r ° q)

Answer 1

\[q(x) = x ^{2} + 3\]\[r(x) = \sqrt{x+2}\]

Answer 2

(q ° r )(2) = 3
(r ° q)(2) = 7

Answer 3

is it right ?

Answer 4

no

Answer 5

\[q\circ r(2)=q(r(2))\] first \(r(2)=\sqrt{2+2}=\sqrt4=2\) and then \[q(r(2))=q(2)=2^2+3\]
i think you had them backwards

Answer 6

yeah i had, fortunally i realized before answer it
