Which of the following is a true statement about functions? A. If fand g are functions, then (fog)(x) = (gof)(x).
B. If fis a function, then
3f(x) = f(3x)
O c. If fand gare functions, then
fab) = f(a)g(b).
D. If fand gare functions, then
(f-g)(x) = f(x) - g(x).

is there more to this question?

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
