Q. Find the inverse function in slope-intercept form (mx+b) :f(x)=2x+2Answer: f−1(x)=
Write function as y=2x+2: To find the inverse function, we first write the function as y=2x+2, where y is the output and x is the input.
Swap x and y: Next, we swap the roles of x and y to find the inverse. This means we replace y with x and x with y, giving us x=2y+2.
Solve for y: Now, we need to solve for y to get the inverse function in slope-intercept form (y=mx+b). Subtract 2 from both sides to isolate the term with y on one side: x−2=2y.
Divide by 2: Divide both sides by 2 to solve for y: (x−2)/2=y.
Simplify to slope-intercept form: Simplify the equation to get the inverse function in slope-intercept form: y=21x−1.
