Given the functions f(x) = log₂(4x) and g(x) = 4ˣ⁻³, which of the following statements is true? (just the x is the exponent, its 4 raised to the power of x, minus 3)
a.Both f(x) and g(x) have a common domain on the interval (0, [infinity]).
b.Both f(x) and g(x) have the same range of (–[infinity], 0].
c.Both f(x) and g(x) have the same intercept of (2, 0).
d.Both f(x) and g(x) increase on the interval of (–4 , [infinity]).
