A collector’s item is purchased for $150 and its value increases by 3% each year. Which graph can be used to determine approximately how many years it will take for the value to double?

The answer is b.

A is in the negatives, and there are no negative years.

B works ; it starts at 150, is positive, and slowly reaches 300

C is exponential and goes to fast.

D starts at 0 not 150

So the answer is b.

Hope this helps!
