Q. What is the inverse of the function h(x)=x+13−x? h−1(x)=□
Understand Inverse Function: Understand the concept of an inverse function. An inverse function, denoted as h−1(x), is a function that reverses the effect of the original function h(x). To find the inverse, we swap the roles of x and y in the original function and then solve for y.
Write Original Function: Write the original function with y instead of h(x). Let y=x+13−x. We will solve for x in terms of y to find the inverse function.
Swap x and y: Swap x and y to find the inverse.Replace y with x and x with y to get the equation for the inverse function: x=y+13−y.
Solve for y: Solve for y in terms of x.To find y, we need to isolate it on one side of the equation. Start by multiplying both sides by (y+1) to get rid of the denominator: x(y+1)=3−y.
Distribute x: Distribute x on the left side of the equation.xy+x=3−y.
Move Terms: Move all terms involving y to one side and the constant terms to the other side.Add y to both sides and subtract x from both sides to get: xy+y=3−x.
Factor out y: Factor out y on the left side of the equation.y(x+1)=3−x.
Divide for y: Divide both sides by (x+1) to solve for y.y=x+13−x.
Write Inverse Function: Write the inverse function.The inverse function is h−1(x)=x+13−x.
