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,

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

What is the inverse of f(x)=3x-1

tatiyna

Answer:

$\frac{(y + 1)}{3}$

Step-by-step explanation:

Call $f(x) = y = 3x - 1$

Now, $y + 1 = 3x$

$\implies \frac{y + 1}{3} = x$

This is the inverse of the given function.

You can cross - verify it by substituting a point, say, $(1,3)$

We see that the point satisfies both the equations.
