How do you graph -(5/2)^x

Question

How do you graph -(5/2)^x ? We have to identify its domain and range as well. 

Answer 1

This is an exponential but since all the y values are negative, it will be a decreasing function.

You can make a table (x,y), e.g. when x=0, y = -1; when x=1, y = -2.5, etc.
