Question

HI PLEASE PLEASE HELP MEEE!!!

Answer 1

Explanation:

in cases where we're not given x = 0, we can use division

`f(x) = a*b^x\\12 = a*b^2\\48 = a*b^4\\(48)/(12)=(ab^4)/(ab^2) \\4 = b^2\\b = \pm2\\12 = a * (2)^2\\12 = 4a\\a = 3\\so\\f(x) = 3(2)^n \\or\\f(x) = 3(-2)^n\\`

since we're never given a case where x's parity is odd, we cannot determine the positivity/negativity of the common ratio

Answer 2

exponentail is 0 times f(x) + x
