SOLUTION: Find the exponential function f(x) = a^x and it gives a graph that is descending with points passing through (-3,8) and (1,1). I have f(-3) = a^-3 = 8, a = 1/2 so f(x) = 1/2 ^-x

: Find the exponential function f(x) = a^x and it gives a graph that is descending with points passing through (-3,8) and (1,1).
I have f(-3) = a^-3 = 8, a = 1/2 so f(x) = 1/2 ^-x.
This doesn't seem correct, can you help?
Thank you so much!! This question is from textbook College Algebra

Find the exponential function f(x) = a^x and it gives a graph that is descending with points passing through (-3,8) and (1,1).
I have f(-3) = a^-3 = 8, a = 1/2 so f(x) = 1/2 ^-x...CORRECT
THEN (1,1) IS NOT A POINT ON IT ..
YOU HAVE DONE IT ALRIGHT.CHECK BACK THE PROBLEM
