Question

Please help me solve this.

Answer 1

Answer: j(k(11)) = ±2

Explanation:

j(k(11)

= j(9 - 11) k(11) = 9 - 11, plug 11 into the x.

=
`\sqrt[]{(9-11) + 6}` Plugin the (9 - 11) for x in the j(x).

=
`√(-2+6)`

=
`√(4)`

= ± 2

Answer 2

Answer: 2 or -2

Explanation:

k(11)=9-11

k(11)=-2

j(k(11))=

j(-2)=

(-2+6)^1/2=

4^1/2=2 or -2
