Toby writes an exponential function f(x) that meets the following two conditions: I. The value of f(1) is 6.
II. The value of f(x) doubles for each increase of 1 in the x values.
Which equation could represent the exponential function that Toby wrote?
A f(x) = 3(2)*
B f(x) = 2(6)*
c f(x) = 6(2)*
D f(x) = 2(3)*
