1-3 Function Operations and Composition
Let f(x) = 4x - 7 and g(x) = 5 + 9x. What are f + g and f-g? What are their domains?
о А.
(f + g)(x) = 13x – 2; (f - 9)(x) = 5x + 12; domain of each is all real numbers except - 5
B. (f+g)(x) = 13x – 2; (1-9)(x) = -5x - 12; domain of each is all real numbers.
О С.
(f + g)(x) = 9x + 2: (8 - 9)(x) = 5x + 12; domain of f + g is all real numbers except
domain off-g is all real numbers except
O D. (+g)(x) = 9x + 2; (1-9)(x) = -5x - 12 domain off + g is all real numbers except - 5 domain of f- g is all real numbers except
