Q. Find the inverse function in slope-intercept form (mx+b) :f(x)=5x−15Answer: f−1(x)=
Understand Inverse Function: Understand the concept of an inverse function. An inverse function essentially 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=5x−15
Swap x and y: Swap x and y to find the inverse function.x=5y−15
Solve for y: Solve for y in terms of x.Add 15 to both sides of the equation to isolate the term with y on one side.x+15=5y
Divide and Solve: Divide both sides by 5 to solve for y.y=5x+15
Write in Slope-Intercept Form: Write the inverse function in slope-intercept form.f−1(x)=51x+3
