Question
The inverse of the function 𝑓(𝑥)=8−6𝑥7 is the function:𝑓−1(𝑥)=
Solution
To find the inverse of the function f(x) = 8 - 6x^7, we need to follow these steps:
-
Replace f(x) with y. This gives us y = 8 - 6x^7.
-
Swap x and y. This gives us x = 8 - 6y^7.
-
Solve for y. This is the tricky part. First, we isolate the term with y by subtracting 8 from both sides: -6y^7 = x - 8.
-
Then, we divide both sides by -6 to get y^7 = (8 - x) / 6.
-
Finally, we take the seventh root of both sides to solve for y. This gives us the inverse function: f^-1(x) = ((8 - x) / 6)^(1/7).
