SUMMARY

The function f is defined piecewise as follows: f(X) = x² for X > 3, f(X) = 3X + 4 for 0 < X < 3, and f(X) = X³ + 2 for X < 0. To find (f°f°f)(-1), the calculation proceeds as follows: f(-1) results in 1, then f(1) yields 7, and finally, f(7) produces 49. Therefore, the final result of three compositions of the function f at -1 is definitively 49.

PREREQUISITES
  • Understanding of piecewise functions
  • Knowledge of function composition
  • Basic algebra skills
  • Familiarity with function notation
NEXT STEPS

IF f(X)={x2, X>3 ; 3X+4, 0<X<3 ; X3+2 , X<0 }

find (f°f°f)(-1)

p.s the answer is 49! i don't know how this f(x) includes three terms x2 , 3x+4 and x3+2 And which term i need to use for the (f°f°f)(-1)
