Try Again Your answer is incorrect. (t - s) ( x ) : Your answer is incorrect. (t . s) (x ) : Your answer is incorrect. (t+ s) ( - 2 ): Your answer is incorrect. Suppose that the functions s and t are defined for all real numbers x as follows. s (x) = 3x+6 t (x) = 4x Write the expressions for (t -s) (x) and (t . s) (x) and evaluate (t+s) (-2). (t - 5) (x) = -2 (t's) (xx) = 2x + 8x X 5 ( + + 5 ) ( - 2 ) = - 12
