Since F(X) And G(X) Are Continuous Function

2. Let f and g be functions from D – R. Now, define the functions max{f, g} and
min {f, g} from D – R by
max{f, g}(x) = max{f (x), g(x)}, min{f, g}(x) – min{f(z), g(x) }.
Assume that f and g are both continuous on D.
(a) Show that max{f, 9} := }(f +9) + 2f -gl
(b) Show that min{f, g} := }(f + 9) – Alf – gl.Math
