There are two real number solutions.
The number of real solutions is shown by the number of times the graph intersects the x-axis. The graph of f(x) = x^3 - 3x^2 + 4 passes through x = -1, and bounces off x = 2. This means that x = -1 is a solution, and x = 2 is also a solution (of multiplicity 2).

Answer:

two real number solutions
