Q. What is the inverse of the function f(x)=3x−2? f−1(x)=
Replace f(x) with y: To find the inverse of the function f(x)=3x−2, we need to solve for x in terms of y, where y=f(x). We start by replacing f(x) with y:y=3x−2
Isolate x on one side: Next, we need to isolate x on one side of the equation. To do this, we'll add 2 to both sides of the equation:y + 2 = 3x - 2 + 2y + 2 = 3x
Divide both sides by 3: Now, we divide both sides of the equation by 3 to solve for x: (y+2)/3=x
Inverse function of f(x): The expression we have for x is the inverse function of f(x). We denote the inverse function as f−1(x), so we have:f−1(x)=3x+2
