SOLUTION: Can someone tellme if the graph of g(x)=logbase4(x+3), is an increasing or decreasing function with a vertical asymptote of 3 or -3?? how do i know?

Question 108093: Can someone tellme if the graph of g(x)=logbase4(x+3), is an increasing or decreasing function with a vertical asymptote of 3 or -3?? how do i know?
Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
it is an increasing function because as x gets larger, the log of x gets larger

there is a vertical asymptote at -3 because as x approaches -3 the value of (x+3) approaches zero
...the log of zero is undefined; but the log of a value approaching zero, approaches negative infinity
