The function f(t) = 1600(1.3) represents the change in a quantity over t days.
What does the constant 1.3 reveal about the rate of change of the quantity?

growth is 0.3 0r 30%

Step-by-step explanation:

1.3 is the base b in exponential function, and when b > 1 that means that graph increases.

Exponential growth is also given as y = a (1 + r)^x,

so instead b it is 1 + r where r is rate of growth because of + sign.

i think it might be a but you might want a second opinion
