Lf f(x) = 5x, what is f^-1(x)?

Nonamiya [84]

Answer: $f^{-1}(x)=\frac{x}{5}$

Step-by-step explanation:

By definition the domain of an inverse function $f^-1(x)$ is the range of f(x) and the range of the inverse function is equal to the domain of the principal function f(x).

If you have a function $f(x)=5x$ , then to find the inverse function, follow these steps:

1. Make $y=f(x)$

$f(x)=y=5x$

$y=5x$

2. Solve for the variable "x":

$x=\frac{y}{5}$

3. Exchange the variable "x" with the variable "y":

$y=\frac{x}{5}$

4. Exchange "y" with $f^{-1}(x)$ . Then the inverse function is:

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

If there are 420 students surveyed, which equation can be used to find the number of students s who prefer rap? Pop: 5/8 Jazz: 1

Aleksandr [31]

Answer:

B. $s=\dfrac{1}{4}\times420$

Step-by-step explanation:

Total number of students surveyed = 420

Of which only $\dfrac{1}{4}$ prefer rap.

So, the number of people who like rap is the product of the fraction of people who prefer rap and the total number of students.

$\text{Number of students who prefer rap}=s=\dfrac{1}{4}\times420\\\Rightarrow s=105$

The number of students that prefer rap is 105

So the equation is $s=\dfrac{1}{4}\times420$ .
