Q. Find the inverse function in slope-intercept form (mx+b) (\mathrm{mx}+\mathrm{b}) :\newlinef(x)=5x15 f(x)=5 x-15 \newlineAnswer: f1(x)= f^{-1}(x)=
  1. Understand Inverse Function: Understand the concept of an inverse function. An inverse function essentially reverses the operation of the original function. If f(x)=yf(x) = y, then f1(y)=xf^{-1}(y) = x. To find the inverse function, we need to solve for xx in terms of yy.
  2. Replace with yy: Replace f(x)f(x) with yy to make the equation easier to work with.\newliney=5x15y = 5x - 15
  3. Swap x and y: Swap x and y to find the inverse function.\newlinex=5y15x = 5y - 15
  4. Solve for y: Solve for y in terms of x.\newlineAdd 1515 to both sides of the equation to isolate the term with yy on one side.\newlinex+15=5yx + 15 = 5y
  5. Divide and Solve: Divide both sides by 55 to solve for yy.y=x+155y = \frac{x + 15}{5}
  6. Write in Slope-Intercept Form: Write the inverse function in slope-intercept form.\newlinef1(x)=15x+3f^{-1}(x) = \frac{1}{5}x + 3
