Question

Exponential Function help?

Answer 1

Please try with this formula:
\[y\left( x \right) = A{e^{ - Bx}}\]
and use your data, in order to find the constants A and B

Answer 2

what values would I input?

Answer 3

I think you have to input this values pairs:
y(0) = 3500,namely x = 0 and y=3500
and:
y(2) = 2000,
namely x= 2 and y=2000

Answer 4

Since you have two unknown constants then the two conditions above are suffice, in order to find the values of A and B

Answer 5

I'm confused... so what would the function be?

Answer 6

for example, if I set x= 0 and y = 3500, I get:
\[3500 = A\]
so A = 3500

Answer 7

whereas if I set x=2 and y=2000, I get:
\[2000 = A{e^{ - 2B}} = 3500 \cdot {e^{ - 2B}}\]
then, what is B?
