Can someone make sure I did this right?
Suppose that the functions r and s are defined for all real numbers x as follows.
r(x)=x+6
s(x)=2x4
Write the expressions for (s+r)(x) and (sr)(x) and evaluate (s.r)(1)
(s+r)(x)=(2x4)+(x+6)
sr)(x)=(2x4)(x+6)
(s.r)(1)= 2(x2) over x+6

Best ResponseYou've already chosen the best response.0So it would be (s+r)(x)= (2xx)+(4+6) (sr)(x)=2xx)(4+6)

Best ResponseYou've already chosen the best response.0For the last part I know I got wrong because my thing doesn't have a fraction sign so I know that that can't be my answer.

Best ResponseYou've already chosen the best response.0\[(s+r)(x)=(2x4)+(x+6)=3x+2\]

Best ResponseYou've already chosen the best response.0I'm confused... so that would be for the first one?
