Best ResponseYou've already chosen the best response.0f−1(x) = The quantity of seven x minus five, over three f−1(x) = The quantity of seven x plus five, over three −f−1(x) = Seven over the quantity of three x plus five f−1(x) = Seven over the quantity of five minus three x

Best ResponseYou've already chosen the best response.0LOL, i'm lost? what do you mean whats the solution A. f−1(x) = The quantity of seven x minus five, over three B. f−1(x) = The quantity of seven x plus five, over three C. −f−1(x) = Seven over the quantity of three x plus five D .f−1(x) = Seven over the quantity of five minus three x

Best ResponseYou've already chosen the best response.0\[f(x)=\frac{ 7x5 }{ 3}\\ switch \ x\ and\ f(x)\\ x=\frac{ 7f(x)5 }{ 3 }\\solving \ for\ f(x)\\f(x)=\frac{ 3x+5 }{ 7}\\putting\ f(x)= inverse\ f(x)\\ \therefore \ inverse\ f(x)= \frac{ 3x+5 }{ 7 }\]

Best ResponseYou've already chosen the best response.0\[given\ f(x) = \frac{ 3x+5 }{ 7}\\ switch\ x\ and \ f(x)\\ i.e. x \ becomes\ f(x) \ and \ f(x) \ becomes\ x\\ x=\frac{ 3f(x)+5 }{ 7},\ solve\ for\ f(x)\\7x=3f(x)+5\\7x5=3f(x)\\f(x)=\frac{ 7x5 }{ 3 }\\replace\ f(x) \ by\ inverse\ f(x)\\i.e.,\ inverse\ f(x)=\frac{ 7x5 }{ 3 }\\clearly\ option\ A \ is\ Correct!\]
