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
