You can put this solution on YOUR website! Briefly describe how the graph can be obtained from the graph of a basic logarithmic function. Then graph the function. Give the domain and the vertical asymptote of each function. f(x) = 5 - 2 log (x+1)
 ***
 Basic log(x) function:
 vertical asymptote: x=0 or y-axis
 domain:(0,∞)
 point on curve: (1,0)
 ..
 -2log(x+1)
 basic curve moves one unit to the left
 curve stetches 2 units
 negative sign results in curve flipping around the x-axis to its mirror image
 vertical asymptote: x=-1
 domain:(-1,∞)
 point on curve: (0,0)
 ..
 5-2log(x+1)
 entire curve raised vertically 5 units
 vertical asymptote: x=-1
 domain:(-1,∞)
 point on curve: (0,5)
 ..
 Sorry, I don't have the means to draw the curve for you.
