It is Given that f(x) = log₂ (x + 4), so the value of f(3) is log₂ (7) or 2.807.
<h3>What is a logarithm?</h3>When you raise a number with an exponent, there comes a result.
Let's say you get
a^b = c
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'
Given ;
f(x) = log₂ (x + 4)
we need to find f(3)
substitute x = 3 in f(x)
f(x) = log₂ (x + 4)
f(3) = log₂ (3 + 4)
f(3) = log₂ (7)
Hence, f(3) = 2.807
