What is the domain of log base 4 of (x+3) ?

all real numbers less than - 3

all real numbers greater than - 3

all real numbers less than 3

all real numbers greater than 3

Domain is the set of numbers you can use for x

log_4 (x+3) = y means

I mean it translates to

4^y=x+3

remember that x^m≥0 for all real values of x and m

it actually can equal 0 only when x=0 or when x is very small

so

therfor since 4^y>0, x+3>0 as well

solving we get

x>-3

all rea lnumbers greater than - 3
