Question

The function f(x)= 2 x 5^x can be used to represent the curve through the points (1, 10), (2, 50), and (3, 250). What is the multiplicative rate of change of the function ?

Answer 1

I think the multiplicative rate of change of the function is 5.
because to get the y coordinate of (2,50) we multiply the y coordinate of (1,10) by 5, similarly to get the y coordinate of (3,250) we multiply that of (2,50) by 5
