Q. Find the inverse function in slope-intercept form (mx+b) :f(x)=−23x+9Answer: f−1(x)=
Replace with y: To find the inverse function, we first replace f(x) with y to make the equation easier to work with.y=−(23)x+9
Swap x and y: Next, we swap x and y to find the inverse function. This means we replace y with x and x with y in the equation.x=−(23)y+9
Solve for y: Now, we need to solve for y to get the inverse function in slope-intercept form y=mx+b. First, we'll move the term involving y to one side and the constant to the other side.23y=−x+9
Isolate y: To isolate y, we divide both sides of the equation by (23), which is the same as multiplying by the reciprocal, 32.y=(−32)x+(32)⋅9
Simplify constant term: Simplify the constant term (32)⋅9 to get the final inverse function.y=(−32)x+6
