Understand Composition of Functions: Understand the composition of functions. The composition of two functions f and g, denoted as (f@g)(x), means that we first apply g to x, and then apply f to the result of g(x). So, (f@g)(x)=f(g(x)).
Find g(0): Find g(0). We are given g(x)=4x. To find g(0), we substitute x with 0. g(0)=4×0=0.
Find f(g(0)): Find f(g(0)). Now that we know g(0)=0, we need to find f(0). We are given f(x)=x+6. So, we substitute x with 0. f(0)=0+6=6.
Find (f@g)(0): Find (f@g)(0).Since we have found that g(0)=0 and f(0)=6, we can now find (f@g)(0) which is f(g(0)).(f@g)(0)=f(0)=6.
