Understand Function Composition: Understand the composition of functions. The composition of two functions (f∘g)(x) means that we first apply g to x, and then apply f to the result of g(x). In mathematical terms, (f∘g)(x)=f(g(x)).
Calculate g(0): Calculate g(0).We need to find the value of g(x) when x=0. Since g(x)=x2+3, we substitute x with 0.g(0)=(0)2+3=0+3=3.
Calculate f(g(0)): Calculate f(g(0)). Now that we have g(0)=3, we need to find f(g(0)) which is f(3). Since f(x)=x+5, we substitute x with 3. f(3)=3+5=8.
Conclude (f@g)(0): Conclude the value of (f@g)(0). We have found that f(g(0))=f(3)=8. Therefore, (f@g)(0)=8.
