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

Answer:
parallel means that the line has the same slope as
Slope point formula :
y - y1 = m (x - x1)
m represents the slope.
x and y represents the point in the form (x, y).
Since the slopes are the same we can substitute the slope into the formula:
then we can substitute our point (2, - 5)
Final answer:
Change the - 5 to positive.
Leave y by it's own and subtract 5 to get rid of it. Do this both sides to make it equal.
