Composite functions and notation Let ?f(x)=x? -4, g(x)=x? and ?F(x)=1/(x-3)?. Simplify or evaluate the following expressions. g(1/z)
Step by step solution Step 1 of 1 If we want to find the value of func tion (x) f o =1/z we must use this value in the relation for the fun ction (x).This is very easy, just follow the next steps: 3 He nce, g(x)=x 3 g(13z)=(1/z) = 13 z = z3 1 1 n So the final value of the function g (1/z) is z3. If we use the rule xn= x , we can write it as z .
