The original function, f(x) = 2x - 1, can be rewritten as f(x) = 2(x) + (-1).
To shift it up three units, we add 3 to the function, giving us f(x) = 2(x) + (-1) + 3 = 2x + 2.
To increase the slope by a factor of 3, we multiply the coefficient of x by 3, resulting in f(x) = 3 * 2x + 2 = 6x + 2.
Therefore, the correct answer is B. f(x) = 6x + 2.
rewrite f(x) = 2x - 1 shifted up three units and the slope increased by a factor of 3
