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.
