Write an exponential function in the form y=ab^x that goes through points (0, 13) and (2, 325).

Question

Please help me!.....................

Answer 1

a = 13. b^0 = 1, y=a(1), 13 = a

325 = 13(b)^2

b^2 = 325/13 = 25

b = sqr25 = 5

y=13(5)^x is the exponential equation going through the two given points
