Let \(f(n) = \left\{ \begin{array}{cl} \lfloor n \rfloor & \text{ if }n \geq 4, \\ \lceil n \rceil & \text{ if } n < 4. \end{array} \right.\)Find \(f\left(\frac{\pi}{3}\right) + f(\sqrt{45}) + f(8^{2/3})\).

pi/3 = 1.047       roof function means = 2

sqrt45 = 6.7       floor function means = 6

82/3 = 4              floor functionmeans  = 4           2+ 6 + 4 = 12     (????    )
