Question

(07.08) f(x) = log₂ (x + 4), what is f¹(3)? (2 points)

Answer 1

It is Given that f(x) = log₂ (x + 4), so the value of f(3) is log₂ (7) or 2.807.

What is a logarithm?

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

$b = \log_a(c)$

'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
