Question 1082213: Please help me solve this question: giv aformula for exponential function in the the from f(x)=C*a^x passing through each pair of points. a) (0,13) & (4,31213) and b) (1,16) & (3,9).
Thank you

a)
We need to solve the system:
1) C = 13
2)C*a^4 = 31,213
So C = 13 and a^4 = 2,401
a = 7
b)
We need to solve the system:
1) C*a = 16
2)C*a^3 = 9
So a^2 = 9/16
a = 3/4 and C = 64/3
