Preview of Differential Equations: 

Given each of the following equations involving a function f, find a possible formula for f(x).

$f\text{'}\left(x\right)=f\left(x\right)$

Step-by-Step Solution

Answer

The possible formula for the function $f\text{'}\left(x\right)=f\left(x\right)$ is $f\left(x\right)=e^x$.

Step 1. Given Information.

The function: $f\text{'}\left(x\right)=f\left(x\right)$

Step 2. Consider the function.

Consider the function,

$$\begin{gathered} f\left(x\right)=e^x \\ f\text{'}\left(x\right)=\frac{d}{dx}{e}^x \\ =e^x \end{gathered}$$

So the function is $f\left(x\right)=e^x$.
