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 contruction 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 linear function.

B. g(x) is exponential; g(x) has the 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)​
