Two different businesses model their profits over 15 years, where x is the year, f(x) is the profits of a garden shop, and g(x) is the profits of a construction materials business. Use the data to determine which function is exponential, and use the table to justify your answer. A. g(x) is exponential; an exponential function increases faster than a linear function.
B. g(x) is exponential; g(x) has a lower starting value and higher ending value.
C. f(x) is exponential; an exponential function increases more slowly than a linear function.
D. f(x) is exponential; f(x) increased less overall than g(x).
