Q. Find the inverse function in slope-intercept form (mx+b) (\mathrm{mx}+\mathrm{b}) :\newlinef(x)=25x16 f(x)=-\frac{2}{5} x-16 \newlineAnswer: f1(x)= f^{-1}(x)=
  1. Understand the problem: Understand the problem.\newlineWe need to find the inverse function of f(x)=25x16f(x) = -\frac{2}{5}x - 16. The inverse function, denoted as f1(x)f^{-1}(x), will undo the operation of f(x)f(x). To find the inverse, we will switch the roles of xx and yy and then solve for yy.
  2. Write the function: Write the function f(x)f(x) as an equation with yy. Replace f(x)f(x) with yy to get the equation in terms of xx and yy. y=(25)x16y = -\left(\frac{2}{5}\right)x - 16
  3. Swap xx and yy: Swap xx and yy to find the inverse.\newlineTo find the inverse function, we switch xx and yy in the equation.\newlinex=(25)y16x = -\left(\frac{2}{5}\right)y - 16
  4. Solve for y: Solve for y.\newlineWe need to isolate yy on one side of the equation to solve for the inverse function.\newlineFirst, add 1616 to both sides of the equation:\newline$x + \(16\) = -\left(\frac{\(2\)}{\(5\)}\right)y
  5. Multiply both sides: Multiply both sides by \(-\frac{5}{2}\) to solve for \(y\). To isolate \(y\), we multiply both sides by the reciprocal of \(-\frac{2}{5}\), which is \(-\frac{5}{2}\). \(\left(-\frac{5}{2}\right)(x + 16) = y\)
  6. Distribute \(-\frac{5}{2}\): Distribute \(-\frac{5}{2}\) on the left side of the equation.\(\newline\)Now we distribute \(-\frac{5}{2}\) to both \(x\) and \(16\).\(\newline\)\(y = \left(-\frac{5}{2}\right)x - \left(\frac{5}{2}\right)\cdot16\)
  7. Simplify the equation: Simplify the equation.\(\newline\)We need to multiply \(-\frac{5}{2}\) by \(16\) to simplify the equation.\(\newline\)\(y = \left(-\frac{5}{2}\right)x - \left(\frac{5}{2}\right)\cdot16\)\(\newline\)\(y = \left(-\frac{5}{2}\right)x - 40\)
  8. Write the inverse function: Write the inverse function in slope-intercept form.\(\newline\)The inverse function in slope-intercept form is:\(\newline\)\(f^{-1}(x) = \frac{-5}{2}x - 40\)
