Question

y=0.5^x - 2 how to graph it from y=0.5^x

Answer 1

Well, a typicaly exponential function is going to look like this:



where the point (0,1) is always there. Now the difference here is you have a number smaller than 1. When you have a number smaller than 1, instead of going down to up, we go up to down, so the graph would look something like this:



Once again, Im always at the point (0,1)

So your graph is going to look like the one above. The exact points you'd have to calculate, but they shouldnt be hard to do. So take that basic graph and move it down 2 units, then maybe point 2 or 3 points to get the curve more exact and youre done.
