Graph: f(x)=2log(base3)(x+3)-1
-
Visit the link I put below and write the first function as 2log(x+3)/log(3)-1

the simplest way would be to plug in a few x values and solve for f(x). you can then plot this solution on the y axis and your plugged in values on the x axis. try a few values spanning different scales to see what happens
