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. x f(x) g(x) 1995 $69,682.50 $72,429.27 2000 $78,943.50 $79,967.77 2005 $88,204.50 $88,290.88 2006 $90,056.70 $90,056.70 2007 $91,908.90 $91,857.83 2010 $97,465.50 $97,480.27 f(x) is exponential; an exponential function increases more slowly than a linear function. f(x) is exponential; f(x) increased more overall than g(x). g(x) is exponential; g(x) has a higher starting value and higher ending value. g(x) is exponential; an exponential function increases faster than a linear function.
