first we have to do g(18), then evaluate the number that we get in h
[tex]\sqrt[]{18-2}=\sqrt[]{16}=4[/tex][tex]x^2+11=4^2+11=16+11=27[/tex]so the a is 27
[tex]b)g(h(4))[/tex][tex]x^2+11=4^2+11=16+11=27[/tex][tex]\sqrt[]{27-2}=\sqrt[]{25}=5[/tex]the b is 5
[tex]c)(g\circ g)(11)[/tex][tex]\sqrt[]{11-2}=\sqrt[]{9}=3[/tex][tex]\sqrt[]{3-2}=\sqrt[]{1}=1[/tex]the c is 1
[tex]d)h(h(0))[/tex][tex]x^2+11=0+11=11[/tex][tex]11^2+11=121+11=132[/tex]the d is 132
[tex]e)(h\circ g)(38)[/tex][tex]\sqrt[]{38-2}=\sqrt[]{36}=6[/tex][tex]6^2+11=36+11=47[/tex]the e is 47
[tex]f)(g\circ h)(0)[/tex][tex]x^2+11=0^2+11=11[/tex][tex]\sqrt[]{11-2}=\sqrt[]{9}=3[/tex]the f is 3
