Best ResponseYou've already chosen the best response.3f(x) is same as y so replace f(x) with y \[\huge\rm\color{ReD}{ y}=\frac{ 122\color{blue}{x} }{ 3 }\] to find inverse(f^{1}(x)) `switch x and y` \[\huge\rm\color{blue}{ x}=\frac{ 122\color{red}{y} }{ 3 }\] now solve for y

Best ResponseYou've already chosen the best response.3do you know how to solve that equation for y ?

Nnesha

Best ResponseYou've already chosen the best response.3first we nee to get rid of the denominator at right side so multiply both sides by 3

Best ResponseYou've already chosen the best response.0substitute y for f(x) then solve x in terms of y then switch x and y and then replace the y with f^1(x)

Nnesha

Best ResponseYou've already chosen the best response.3yes right so how would you solve x in terms of y ?

Best ResponseYou've already chosen the best response.3\[\huge\rm\color{blue}{ x}=\frac{ 122\color{red}{y} }{ 3 }\] first multiply both sides by 3

Best ResponseYou've already chosen the best response.3\[\huge\rm\color{green}{3}·\color{blue}{ x}=\frac{ 122\color{red}{y} }{\cancel{ 3} }·\color{green}{\cancel{3}}\] multiply both sides by 3 at right side 3 cancels out then u get \[\huge\rm 3x=122y\] now move the 12 at left side how would you do that would add ,subtract,multiply or divide 12 both sides ?

Nnesha

Best ResponseYou've already chosen the best response.3hmm no it's `12 2y` 12 is subtracting with 2y so you should apply the opposite of `subtraction` which is addition so add 12 both sides

Best ResponseYou've already chosen the best response.0ok add negative 12 to both or positive

Nnesha

Best ResponseYou've already chosen the best response.3it's negative 12 at right side so what is opposite of negative ?

Nnesha

Best ResponseYou've already chosen the best response.3yes so to cancel out 12 you should add

Best ResponseYou've already chosen the best response.3DON"t add 3x and 12 it's not 15 okay! :=)

Best ResponseYou've already chosen the best response.0ok well 12 and 12 make 24

Nnesha

Best ResponseYou've already chosen the best response.3to solve for y we need to move 12 and 2 to the left side so we should cancel out the 12

Nnesha

Best ResponseYou've already chosen the best response.3and you can't add 3x with 12 so that would stay the same dw:1442718149403:dw

Nnesha

Best ResponseYou've already chosen the best response.3now one and last step cancel out the 2 from right side how would you do that ?

Best ResponseYou've already chosen the best response.3it's 2 · y (multiplication) apply the opposite of multiplication

Best ResponseYou've already chosen the best response.3\[y=\frac{ 3x12 }{ 2 } =\] is same as \[y=\frac{ 3 x}{ 2 } \frac{ 12 }{ 2 }\] you can divide 12/2

Best ResponseYou've already chosen the best response.0lol yea i just started school so we are now started doing these and i got a 2/26 on my review and

Best ResponseYou've already chosen the best response.3okay got 2 mints divide 12/2 = ?

Nnesha

Best ResponseYou've already chosen the best response.3yes so \[y=\frac{ 3 x}{ 2 } 6\]

Best ResponseYou've already chosen the best response.3and let me tell you how to put that inot the calculator x=(122y)/3 (PARENTHESES FOR SAFETY
