What is the end behavior of f(x) = –0.45x + 3? a) as x decreases without bound, f(x) decreases without bound. as x increases without bound, f(x) approaches the line y = 3. b) as x decreases without bound, f(x) increases without bound. as x increases without bound, f(x) approaches the line y = 3. c) as x decreases without bound, f(x) approaches the line y = 3. as x increases without bound, f(x) decreases without bound. d) as x decreases without bound, f(x) approaches the line y = 3. as x increases without bound, f(x) increases without bound.
