Suppose that the functions and are defined for all real numbers as follows. r(x)=3x^(2) s(x)=2x write the expressions for (r-s)(

nirvana33 [79]

The expression for (r-s)(x) is found by subtracting s from r. That difference is $3 x^{2} -2x$ . The expression for (r+s)(x) is found by adding them, which is $3 x^{2} +2x$ . Now we are told to evaluate (r*s)(x) which means they want us to multiply those and state the "new" expression that results. $(3 x^{2} )(2x)=6x^3$ . There you go!
