Exercise 74 Page 316

Begin by finding f(- x).

g(x)=sqrt(- x)+3

Practice makes perfect
We want to write a rule for g that represents the indicated transformations of the graph of f. f(x)=sqrt(x), g(x)=f(- x)+3

To do so, we should first find f(- x) by substituting - x for x into f. f(x)=sqrt(x) ⇓ f( - x)=sqrt(- x) Finally, we will substitute sqrt(- x) for f(- x) into g(x)=f(- x)+3. g(x)=f(- x)+3 ⇓ g(x)= sqrt(- x)+3
