Q. Find the inverse function in slope-intercept form (mx+b) (\mathrm{mx}+\mathrm{b}) :\newlinef(x)=3x+15 f(x)=-3 x+15 \newlineAnswer: f1(x)= f^{-1}(x)=
  1. Write function as equation: To find the inverse function, we first write the function as an equation with yy instead of f(x)f(x):y=3x+15y = -3x + 15
  2. Swap x and y: Next, we swap x and y to find the inverse: x=3y+15x = -3y + 15
  3. Solve for y: Now, we solve for y to get it in slope-intercept form y=mx+by = mx + b:\newlineAdd 3y3y to both sides:\newline3y=x+153y = -x + 15
  4. Divide by 33: Divide both sides by 33 to solve for yy:y=(13)x+5y = \left(-\frac{1}{3}\right)x + 5
  5. Inverse function in slope-intercept form: The inverse function in slope-intercept form is: f1(x)=(13)x+5f^{-1}(x) = \left(-\frac{1}{3}\right)x + 5
