Question

The table below shows the functions to represent the sale f(t), in thousands, of four companies in t years.

Answer 1

Hi there

the companies showed an exponential growth in sale are

Company C with
f(t) = 1.26t

Company D with
f(t) = 1.09t

Because
1+r where r is the rate of growth

the rate of growth of Company c is 1+26%

The rate of growth of company D is
1+9%


So it's option d

Good luck!
