Question

verify the functions are inverses:
f(n)=-16+n/4 g(n)=4n+16
can anyone explain how I would go about answering this problem step-by-step

Answer 1

@sammixboo

Answer 2

Compute f(g(n)) and g(f(n)) and verify that they are equal to n

Answer 3

\[
f(g(n))=\frac{1}{4} (4
n+16)-4=n
\]

Answer 4

\[
g(f(n))=4
\left(\frac{n}{4}-4\right)+
16=n
\]

Answer 5

@eliassaab thank you soooo much can you help me with one more?
f(x)=x^2-9
g(x)=x+3

Answer 6
