To find f(13), we first need to use the given function definition: f(x) = log2(x) + 4.
Now, we will substitute 13 in place of x:
f(13) = log2(13) + 4
The next step is to calculate log2(13). The logarithm log2(13) is the power to which the base 2 must be raised to produce the number 13. This value is not a whole number, but it can be calculated or estimated using a calculator. Approximately, log2(13) ≈ 3.7.
Now, we can plug this back into our equation:
f(13) ≈ 3.7 + 4
Therefore, f(13) ≈ 7.7.
In conclusion, after evaluating the logarithm and adding 4, we find that f(13) is approximately 7.7.
