$24, - 5, 7, 5$ $24,-5,7,5$

Explanation:

$f (g (- 2)) means evaluate g(x) for x = -2 then evaluate$ $f(g(-2))" means evaluate g(x) for x = -2 then evaluate"$
$f(x) for x = g(-2)$ $"f(x) for x = g(-2)"$

$\Rightarrow f (g (- 2)) = f (1 + 4) = f (5) = 25 - 1 = 24$ $rArrf(g(-2))=f(1+4)=f(5)=25-1=24$

$the same process applies to the remaining questions$ $"the same process applies to the remaining questions"$

$\Rightarrow g (f (- 2)) = g (4 - 1) = g (3) = 1 - 6 = - 5$ $rArrg(f(-2))=g(4-1)=g(3)=1-6=-5$

$\Rightarrow g (g (2)) = g (1 - 4) = g (- 3) = 1 + 6 = 7$ $rArrg(g(2))=g(1-4)=g(-3)=1+6=7$

$\Rightarrow g (2 g (1)) = g (2 \times - 1) = g (- 2) = 1 + 4 = 5$ $rArrg(2g(1))=g(2xx-1)=g(-2)=1+4=5$
