I need help setting this up...
A function (f) is given by the formula...f(x)=A*e^(k*x) for constants (A) and (k) we also know that f(5)=2 and f(8)=5. Find numerical values for the constants A and k.

Answer 1

@dan815 Found it in closed questions :)

Answer 2

Would u use matrices

Answer 3

f(x)=A*e^(k*x)
2=A*e^(5k)
k=(ln2/A )/5
plug and solve
5=A*e^(8k)
