Example 16 Let F X X2 And G X 2x 1 Find F G Fg F G Step 1. the objective is to find the true statements of the following. a let a∈r. let f,g be two functions defined on r. which of the following statements must be true? select all that apply. if limx→af (x) exists then limx→aef (x) exists if limx→a f (x)=1 and limx→1g(x)=2 then limx→a f (g(x))=2 if f and g are not continuous at. Our expert help has broken down your problem into an easy to learn solution you can count on. question: determine the following statements are true or false. let f,g be two functions defined on r. let a∈r. a) if f and f g are continuous at a, then g is continuous at a. b) if f2 is continuous at a, then f is continuous at a.
Example 16 Let F X X2 And G X 2x 1 Find F G Fg F G Let f, g: r → r be two function defined as f (x) = | x | x and g (x) = | x | − x, for all x ϵ r. then find f o g , hence find f o g ( 5 ) , f o g ( − 3 ) . view solution. Answer the operation (f∘g)(x) represents the composition of the functions f and g, which means applying the function g first and then applying the function f to the result. in continue reading. If f :a → b and g : c → d. then (fog) (x) will exist if and only if the co domain of g = domain of f i.e d = a and (gof) (x) will exist if and only if co domain of f = domain of g i.e b = c. in our case, the co domain of g is r and the domain of f is also r so (fog) (x) is defined. composition of function: (fog) (x) = f[g(x)] calculations:.
