What is the inverse of f(x) = -5x-4
elena55 [62]

Answer:

\displaystyle f^{-1}(x) = -\frac{1}{5}x - \frac{4}{5}.

Step-by-step explanation:

The question has provided an expression for the function f(x) and is asking for its inverse, f^{-1}(x).

Based on the definition of inverse functions,

f(f^{-1}(x)) = x.

Let y = f^{-1}(x).

f(y) = x.

-5 y - 4= x.

Solve this equation for f^{-1}(x) = y:

-5y = x +4.

\displaystyle y = (-\frac{1}{5})\cdot (x + 4) = -\frac{x}{5} -\frac{4}{5}.

However, f^{-1}(x)=y As a result,

\displaystyle f^{-1}(x) = -\frac{x}{5} -\frac{4}{5}.
