Solve the problem.The following numerical representation for f computes the average number of hours of television watched per day based on year of birth x.
Give a numerical representation for a function g that computes the average number of hours of television watched per day for the year x, where 
corresponds to the birth year 1975. Write an equation that shows the relationship between f(x) and g(x).
A. 
f(x) = g(x - 1900)
B. 
f(x) = g(x + 1975)
C. 
f(x) = g(x - 1975)
D. 
f(x) = g(x) - 1975
