Best ResponseYou've already chosen the best response.0To find the inverse of a function you are first gonna need to replace f(x) with y. Then you have to flip the x and y variables and solve for y. @sherlocked1270

Best ResponseYou've already chosen the best response.1\(\color{blue}{\text{Originally Posted by}}\) @sunleaf01 f(x) = 2x − 8 y = 2x − 8 x = 2y − 8 x+8=2y and so on.. \(\color{blue}{\text{End of Quote}}\) After this step we are supposed to divide 2 throughout the equation.

Best ResponseYou've already chosen the best response.2how did u get tht??? y = 2x + 8 switch x and y x = 2y + 8 x  8 = y x/2  4 = y now stick inverse notation

Best ResponseYou've already chosen the best response.1there's an error. Everything is fine until x+8=2y divide 2 throughout the entire equation to have y by itself the fraction part is correct, but we should have a 4

Best ResponseYou've already chosen the best response.2u will get x  8 = 2y so (x  8)/2 = y x/2  8/2 = y x/2  4 = y

Best ResponseYou've already chosen the best response.0so u were saying that you have to get rid of the F(x) but in the answers that are provided It has f(x) f^1(x)=1/2x8 f^1(x)=1/2x+4 f^1(x)=1/2+8 f^1(x)=2x+16

Best ResponseYou've already chosen the best response.2see my just previous reply... i ended with y = x/2 + 4 replace y from f^1(x) so it woud be f^1(x) = x/2 + 4
