Suppose that the functions f and g are defined for all real numbers x as follows. f(x)=2x+5 g(x)=6x Write the expressions for (g+f)(x)


Suppose that the functions f and g are defined for all real numbers x as follows.
f(x)=2x+5
g(x)=6x
Write the expressions for (g+f)(x) and (g-f)(x) and evaluate (g. f)(-1).
