Question

How do I find an exponential function with 2 given points?

ex: (1,12) (4,768)

Answer 1

\[3(4^{x})\]

Answer 2

oh well i had the whole thing typed out, then my screen froze and i lost it

y = 3(4^x)

Answer 3

Do you mind explaining how you came to that answer (if it's not too much trouble)?

Answer 4

y = a*b^x
plug in x and y from 2 points to get 2 equations
then use substitution to solve for a and b

Answer 5

Alright, thanks a lot.
