Question

Please help me solve this.

Answer 1

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 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.

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

= $\sqrt{-2+6}$

= $\sqrt{4}$

= ± 2
