## Introduction

In mathematics, a piecewise function is a function whose domain is partitioned into subdomains, on each of which the function restricts to a different continuous real-valued function.

## What is f3?

In mathematics, evaluate means to calculate the value of a given expression. The function f3 is a piecewise function defined as follows:

fx(x) = { 11 if x<8,

8 if x≥8 and x<125,

125 if x≥125 and x<16,

16 if x≥16}

The value of f3 represents the function fx evaluated at the point x=3. Therefore, the value of f3 is 11.

## How to calculate f3

In order to calculate f3, you will need to first determine the function’s domain. This is the set of all values for which the function produces a result. For this function, the domain is all real numbers.

Next, you will need to find the value of f3 when x = 11. To do this, you will plug 11 in for x in the function and simplify. This should give you a result of 8.

Now, you will need to find the value of f3 when x = 8. To do this, you will plug 8 in for x in the function and simplify. This should give you a result of 125.

Finally, you will need to find the value of f3 when x = 16. To do this, you will plug 16 in for x in the function and simplify. This should give you a result of -1.

putting all these results together, we can see that f3 is equal to 8 when x = 11, 125 when x = 8, and -1 when x = 16.

## What is the value of f3 for the given function?

The value of f3 for the given function is 8.

## Conclusion

After evaluating the function for various values of x, it can be concluded that f3 11 8 125 16 represents the value of f(x) for x=3.
