Instructions: type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar(s).
consider the functions f(x)=x^2+9x and g(x)=1/x.
f(g(-1)) is
g(f(1/2)) is

-8

2/19

Step-by-step explanation:

We must substitute x=-1 into g(x) and then the answer of g(x) we must substiute as x into f(x). Similarly we must substitute x=1/2 into f(x) and the answer as x into g(x):

1. x=-1 into g(x)

substitute x=-1 into f(x)

2. x=1/2 into f(x)

substitute x=19/2 into g(x)
