Understand Composition of Functions: First, we need to understand what the composition of functions (f@g)(x) means. It means that we first apply the function g to x, and then apply the function f to the result of g(x). So, (f@g)(x)=f(g(x)).
Find g(0): Given the functions f(x)=6x and g(x)=x2+4x, we need to find g(0) first, since we are looking for (f@g)(0).
Calculate g(0): To find g(0), we substitute x with 0 in the function g(x): g(0)=02+4⋅0.
Find f(g(0)): Calculating g(0) gives us g(0)=0+0, which simplifies to g(0)=0.
Calculate f(0): Now that we have g(0), we need to find f(g(0)). Since g(0)=0, we need to find f(0).
Final Result: To find f(0), we substitute x with 0 in the function f(x): f(0)=6×0.
Final Result: To find f(0), we substitute x with 0 in the function f(x): f(0)=6×0.Calculating f(0) gives us f(0)=0, which means that (f@g)(0)=f(g(0))=f(0)=0.
