GRAPHS AND FUNCTIONS Sum, difference, and product of two functions Suppose that the functions g and h are defined for all real numbers x as follows. g (x) =2x+3 h (x) = 5x Write the expressions for (h - g) (x) and (h-g) (x) and evaluate (h+g) (4). ( h.8) (x ) = 1 ( h - 8) (x) = 0 X 5 ( h + = ) (4) = 1
