Question

List the key features of this exponential function: y= -5(1/3)^x.

Increasing or decreasing? y-int? common ratio? Horizontal Asymptote?

What would happen if the equation was: y= -5(1/3)^x-2?

Answer 1

Answer:

Increasing

y - intercept = -5

Common ratio = ⅓

Horizontal asymptote: y = 0

New equation:

Horizontal asymptote: y = -2
