Look at A
if x = -2, y = -1/9 + 2 never bigger than 2
if x = +2, y = -9 + 2 goes big -
Look at B
if x = -2, y = -1/9 - 2
if x = +2, y = -9 -2 goes big -
Look at C
if x = -2, y = -1/.125+2
if x = 0, y = 2
if x = +2, -.125+2 approaches 2
Look at D also stays close to 2
A is the only one that goes big negative but is never more positive than 2
Which of the following could be an example of a function with a domain (-oo,oo) and a range (-oo,2)? Check all that apply.

B. y= -(3)^x-2
