Which of the following statements is true about the functions f(x)=5x+15 and
g(x)=1/5x-3?
*
A. f(5) = g(5) because f(x) and g(x) are inverse functions.
B. f(-5) = g(5) because f(x) and g(x) are inverse functions.
O c.f(x) and g(x) are inverse functions because f(x) and g(x) have the same domain.
O D. f(x) and g(x) are inverse functions because f g = x and g• f = x.
