Question

Can someone please help with 13 or 14 or both please

Answer 1

`Ans\ 13: \{(d)\ (f\circ g)(1)=26\}\\\\(f\circ g)(1)=f(g(1))\\\\g(1)=3(1)+2=5\\\\\therefore (f\circ g)(1)=f(g(1))=f(5)\\\\\implies (f\circ g)(1)=26\ (i.e.\ 25+5-4)\\\\\hrule \ \\\\Ans\ Q14: \{(e)\ (f+g)(3) = 20\}\\\\(f+g)(3)=f(3)+g(3)\\\\\implies (f+g)(3)=(9+3)+(9-1)\\\\=20`
