what is the inverse function of f(x) = 19/x^3
Answer:
Step-by-step explanation:
1) Replace f(x) with y: y = 19/x^3
2) Interchange x and y: x = 19/y^3
3) Solve this result for y: xy^3 = 19, or y^3 = 19/x, or
y = ∛[19/x]
-1
4. Replace this y with the label f (x) = ∛[19/x]
Answer:
The inverse function of \(f(x) =\frac{19}{x^3}\)
\(f(x)^{-1}=\sqrt[3]{\frac{19}{x}}\)
Step-by-step explanation:
\(f(x) = \frac{19}{x^3}\)
Steps to inverse the functions:
Step 1: x ⇔ y
\(x=\frac{19}{y^3}\)
Step 2 : now solve the equation for y:
\(y^3=\frac{19}{x}\)
\(y=\sqrt[3]{\frac{19}{x}}\)
The above equation is the inverse of the given function f(x).
\(f(x)^{-1}=\sqrt[3]{\frac{19}{x}}\)
