Q. Find the inverse function in slope-intercept form (mx+b) :f(x)=23x+9Answer: f−1(x)=
Understand Inverse Function: Understand the concept of an inverse function. An inverse function reverses the operation of the original function. If f(x)=y, then f−1(y)=x. To find the inverse function, we need to solve for x in terms of y.
Replace with y: Replace f(x) with y to make the equation easier to work with.y=(23)x+9
Swap x and y: Swap x and y to find the inverse function.x=23y+9
Solve for y: Solve for y in terms of x.First, subtract 9 from both sides of the equation.$x - \(9\) = \left(\frac{\(3\)}{\(2\)}\right)y
Multiply by reciprocal: Multiply both sides by the reciprocal of \((\frac{3}{2})\) to solve for \(y\).\[y = \left(\frac{2}{3}\right)(x - 9)\]
Write in slope-intercept form: Write the inverse function in slope-intercept form. \(f^{-1}(x) = \frac{2}{3}x - 6\)
