Graph the exponential function. f(x)= -(5/2)^x

7nadin3 [17]

Answer:

see below

Step-by-step explanation:

Your spreadsheet or graphing calculator can do this for you.

If you want to do it by hand, pick a few values for x, compute the corresponding values of f(x), plot those points, and draw a smooth curve through them. You know the horizontal asymptote is y=0, and the whole graph is in the 3rd and 4th quadrants, since the exponential function has been reflected over the x-axis by the leading minus sign.
