Step-by-step explanation:
The answer will be for every x, y will be 1.25
Question a
g(x) times

divide both sides by √(x-5)



question b

divide both sides by 1+1/x

times by x/x

question c

times both sides by x

question d
the (f*g)(x) collumn seems to have a domain of only x is greater than or equal to 0?
so maybe we squared the whole thing, ya
wait
ah, ya
basically

so f(x)=√x
a.

b.

c.

d.
3.6 because
a^2 =13
the square root of 13 is 3.6 rounded to the nearest tenth
