Thread: Calculus: Exponential Functions

can someone help me with this problem..



well, I thought that f(x)= 2*e^(-x) was pretty close except when x at 2, y is not (2/9) but instead it's .5

any one can help?
thanks..

Well it goes through (0, 2), so


So the curve is .

Again, the curve goes through so,




Thus


Now, we may exclude the negative solution because the curve for this is, to put it mildly, psychotic. Thus
