Please help me solve this.

Answer: 2 or -2
Step-by-step explanation:
k(11)=9-11
k(11)=-2
j(k(11))=
j(-2)=
(-2+6)^1/2=
4^1/2=2 or -2
Answer: j(k(11)) = ±2
Step-by-step explanation:
j(k(11)
= j(9 - 11) k(11) = 9 - 11, plug 11 into the x.
= [tex]\sqrt[]{(9-11) + 6}[/tex] Plugin the (9 - 11) for x in the j(x).
= [tex]\sqrt{-2+6}[/tex]
= [tex]\sqrt{4}[/tex]
= ± 2
