How do you graph a growth/decay equation???? HELP PLEASE

I know the equation for graphing an equation such as these is Y=ab^x but i just don't know where to go from there....
ok, so the starting value of something is 1,515,999 and the rate of change is .001414 (or .1414%). This item is 313 years old and its current price is 2,359,533.75
HOW THE HECK DO YOU GRAPH THAT! Im sorry I've just been freaking out over this for a while...

The shape of the exponential growth graph is that it should have an asymptote at the x axis , pass through (0,a) and curve up on the right.

So for your problem a= 1,515,999
You can label your y intercept as (0,1515999) or label the y axis in millions, and round to 1.5.

Then the second point is (313, 2359533.75) or (313, 2.4) in millions.

Then the equation is y= 1515999(1.001414)^t

You can also see this graph with a graphing calculator.

I hope this helps!
