f(x) = [tex]2^{x}[/tex] - 2 and g is a horizontally scaled function of f. The functions are graphed where f is solid and g is dashed. What is the equation of g?
A. g(x) = [tex]2^{3x}[/tex] - 2
B. g(x) = [tex]2^{\frac{1}{3}x }[/tex] - 2
C. g(x) = [tex]2^{2x} - 2[/tex]
D. g(x) = [tex]2^{\frac{1}{2}x} - 2[/tex]
