+2 crosses the equal sign to become 4y=18-2,as 18-2=16 so you get 4y=16 and finally divide both sides by 4,as 4 goes into 16,4 times,therefore,y=4

Answer:

Option (a) is true.

Step-by-step explanation:

Given the function

$f(x)=x+5$

$g\left(x\right)=x^2-3$

(f∘g)(x) = f(g(x)) = f(x²-3) = (x²-3)+5

= x² + 2

Thus,

f(g(x)) = x² + 2

Therefore, option (a) is true.
