Write the function f as a set of ordered pairs. Give the domain and range of f.f(f) = -6, f(g) = -6, f(h) = -6, f(i) = -6
A. f = {(f, -6), (g, -6), (h, -6), (i, -6)}; D = {-6}; R = {f, g, h, i}
B. f = {(-6, f), (-6, g), (-6, h), (-6, i)}; D = {f, g, h, i}; R = {-6}
C. f = {(-6, f), (-6, g), (-6, h), (-6, i)}; D = {-6}; R = {f, g, h, i}
D. f = {(f, -6), (g, -6), (h, -6), (i, -6)}; D = {f, g, h, i}; R = {-6}
