Replace with y: To find the inverse of the function f(x)=32x−7, we first replace f(x) with y for convenience.So, we have y=32x−7.
Swap x and y: Next, we swap x and y to find the inverse function. This gives us x=32y−7.
Eliminate cube root: Now, we need to solve for y. To do this, we will cube both sides of the equation to eliminate the cube root.So, we have x3=(2y−7).
Isolate y: Next, we isolate y by adding 7 to both sides of the equation.This gives us x3+7=2y.
Divide by 2: Finally, we divide both sides of the equation by 2 to solve for y. This gives us y=2x3+7.
Write inverse function: We now have the inverse function, which we can write as f−1(x)=2x3+7.
