Q. What is the inverse of the functiong(x)=x+4−x−2?g−1(x)=□
Replace with y: To find the inverse of the function g(x)=x+4−x−2, we need to switch the roles of x and y, and then solve for y. Let's start by replacing g(x) with y:y=x+4−x−2
Switch x and y: Now, switch x and y to find the inverse: x=y+4−y−2
Cross-multiply: Next, we need to solve for y. To do this, we'll start by cross-multiplying to get rid of the fraction:x(y+4)=−y−2
Distribute x: Distribute the x on the left side of the equation:xy+4x=−y−2
Combine like terms: Now, we want to get all the terms with y on one side and the constant terms on the other side. Let's add y to both sides and add 2 to both sides: xy+y+4x+2=0
Isolate y: Combine like terms by factoring y out of the terms on the left side: y(x+1)+4x+2=0
Divide both sides: Now, isolate the term with y by subtracting 4x and 2 from both sides:y(x+1)=−4x−2
Find inverse: Finally, divide both sides by (x+1) to solve for y:y=x+1−4x−2
Find inverse: Finally, divide both sides by (x+1) to solve for y:y=x+1−4x−2We have found the inverse function. The inverse of g(x) is:g−1(x)=x+1−4x−2
