g(x) is exponential; an exponential function increases faster than a linear function.
g(x) is exponential; g(x) has a lower starting value and higher ending value.
f(x) is exponential; an exponential function increases more slowly than a linear function.
f(x) is exponential; f(x) increased less overall than g(x).
